The solar system, explained

Our solar system is made up of the sun and all the amazing objects that travel around it.

The universe is filled with billions of star systems. Located inside galaxies, these cosmic arrangements are made up of at least one star and all the objects that travel around it, including planets, dwarf planets, moons, asteroids, comets, and meteoroids. The star system we’re most familiar with, of course, is our own.

Home sweet home

If you were to look at a giant picture of space, zoom in on the Milky Way galaxy , and then zoom in again on one of its outer spiral arms, you’d find the solar system. Astronomers believe it formed about 4.5 billion years ago, when a massive interstellar cloud of gas and dust collapsed on itself, giving rise to the star that anchors our solar system—that big ball of warmth known as the sun.

Along with the sun, our cosmic neighborhood includes the eight major planets. The closest to the sun is Mercury , followed by Venus , Earth, and Mars . These are known as terrestrial planets, because they’re solid and rocky. Beyond the orbit of Mars, you’ll find the main asteroid belt , a region of space rocks left over from the formation of the planets. Next come the much bigger gas giants Jupiter and Saturn , which is known for its large ring systems made of ice, rock, or both. Farther out are the ice giants Uranus and Neptune . Beyond that, a host of smaller icy worlds congregate in an enormous stretch of space called the Kuiper Belt. Perhaps the most famous resident there is Pluto . Once considered the ninth planet, Pluto is now officially classified as a dwarf planet , along with three other Kuiper Belt objects and Ceres in the asteroid belt.

Moons and other matter

More than 150 moons orbit worlds in our solar system. Known as natural satellites, they orbit planets, dwarf planets, asteroids, and other debris. Among the planets, moons are more common in the outer reaches of the solar system. Mercury and Venus are moon-free, Mars has two small moons, and Earth has just one. Meanwhile, Jupiter and Saturn have dozens, and Uranus and Neptune each have more than 10. Even though it’s relatively small, Pluto has five moons, one of which is so close to Pluto in size that some astronomers argue Pluto and this moon, Charon, are a binary system.

Too small to be called planets, asteroids are rocky chunks that also orbit our sun along with the space rocks known as meteoroids. Tens of thousands of asteroids are gathered in the belt that lies between the orbits of Mars and Jupiter. Comets, on the other hand, live inside the Kuiper Belt and even farther out in our solar system in a distant region called the Oort cloud .

Atmospheric conditions

The solar system is enveloped by a huge bubble called the heliosphere . Made of charged particles generated by the sun, the heliosphere shields planets and other objects from high-speed interstellar particles known as cosmic rays. Within the heliosphere, some of the planets are wrapped in their own bubbles—called magnetospheres —that protect them from the most harmful forms of solar radiation. Earth has a very strong magnetosphere, while Mars and Venus have none at all.

Most of the major planets also have atmospheres . Earth’s is composed mainly of nitrogen and oxygen—key for sustaining life. The atmospheres on terrestrial Venus and Mars are mostly carbon dioxide, while the thick atmospheres of Jupiter, Saturn, Uranus, and Neptune are made primarily of hydrogen and helium. Mercury doesn’t have an atmosphere at all. Instead scientists refer to its extremely thin covering of oxygen, hydrogen, sodium, helium, and potassium as an exosphere.

Moons can have atmospheres, too, but Saturn’s largest moon, Titan, is the only one known to have a thick atmosphere, which is made mostly of nitrogen.

Life beyond?

For centuries astronomers believed that Earth was the center of the universe, with the sun and all the other stars revolving around it. But in the 16th century, German mathematician and astronomer Nicolaus Copernicus upended that theory by providing strong evidence that Earth and the other planets travel around the sun.

Today, astronomers are studying other stars in our galaxy that host planets, including some star systems like our own that have multiple planetary companions. Based on the thousands of known worlds spotted so far, scientists estimate that billions of planetary systems must exist in the Milky Way galaxy alone.

So does Earth have a twin somewhere in the universe? With ever-advancing telescopes, robots, and other tools, astronomers of the future are sure to find out.

Essay on Solar System for School Students

• Updated on  
• Dec 23, 2023

Essay on Solar System: Our solar system consists of one Sun and eight (formerly nine) planets. These eight planets are gravitationally bound by the Sun on their orbits. Apart from these eight planets, there are more than 210 known planetary satellites, asteroids, comets, and other icy bodies that are assembled in the Solar system. 

The first four planets are called terrestrial planets (Mercury, Venus, Earth, and Mars) the two gas planets (Jupiter and Saturn), and the other remaining ones are ice giants (Neptune and Uranus.)

Table of Contents

• 2 Inner Planets (Terrestrial Planets):
• 3 Outer Planets (Gas Giants)
• 5 FAQs 

Learn about the smallest planet in our solar system

The Sun is the primary source of light and energy and is about 93 million miles from the Earth. It is the only star in our solar system and one of the more than 100 billion stars in the Milky Way. The surface of the Sun is about 5,500 degrees Celsius (10,000 degrees Fahrenheit) hot and the temperature reaches 15 million Celsius (27 million Fahrenheit). 

In terms of age and size, the Sun is 4.5 billion years old, composed of hydrogen and helium with a diameter of about 865,000 miles which is approximately 1.4 million kilometres. 

Inner Planets (Terrestrial Planets):

The planets that are made of rocks and metals are known as Inner Planets or Terrestrial Planets. These planets are comparatively small in size compared to the other outer planets. The description of these four planets is as follows:

1. Mercury—The Swift Planet

Mercury is the swiftest planet in our solar system which completes an orbit around the Sun in just 88 Earth days. Its proximity to the Sun contributes to extreme temperature variations, from scorching highs to freezing lows. 

With minimal atmosphere, Mercury lacks the protective blanket found on the Earth, exposing its surface to harsh solar radiation. 

2. Venus—The Evening Star or Morning Star

Venus, which is often referred to as the evening star or morning star, depends on its position relative to the Sun. When Venus is trailing the Sun, it is the evening star, visible after the sunset. Conversely, when ahead of the Sun, it is the morning star, appearing before sunrise. 

This dual identity arises from Venus´s orbit, positioning it closer to the Sun than Earth and causing varied visibility during different parts of the orbital journey. 

3. Earth—Blue Planet

The home planet to all living things is Earth. It is the only planet that is known for the existence of life. 

The surface of the Earth is made up of the crust, the core, and the mantle. It is a giant rocky planet with a circumference of about 40,075 kilometers; 71 percent or ¾ th of the Earth is covered with oceans and seas. A large area covered with water makes this planet a Blue Planet. 

4. Mars—Red Planet

The fourth planet of the solar system, Mars, is the most explored planet by the National Aeronautics and Space Administration (NASA.) The reason behind so many missions or research for Mars is to hope for the existence of extraterrestrial life on the planet. 

Apart from the possibility of life on Mars, the planet is also known for its presence of iron oxide that turns the planet reddish in appearance.

Outer Planets (Gas Giants)

5. Jupiter—King of Planets

Jupiter is the first planet of our solar system in the category of outer planets, also known as gas giants. According to NASA, the U.S. government agency, the planet’s size is more than twice that of all other planets combined. 

Except for Jupiter’s size, the solar system’s first outer planet is made up of leftover gases from the formation of the Sun. 

6. Saturn—Ringed Planet

The sixth planet from the Sun is Saturn. It is also known as the ringed planet and the second-largest solar system planet. 

The three distinctive features that make Saturn different from other planets are its huge 145 moons, visibility from the Earth with the naked eye, and the seven main rings named D, C, B, A, F, G, and E from the outward side of the planet. 

7. Uranus—Ice Giant

The seventh planet from the Sun, Uranus, is one of the two ice giants in the list of the outer solar system. The planet is featured with the third largest diameter which makes the planet the third largest in the solar system. 

Other than massive size, Uranus is made up of three dense icy materials, methane, ammonia, and water – above all a small rocky core. 

8. Neptune—Blue Giant

The third largest and eighth planet of the solar system is Neptune. According to NASA, the farthest planet from the Sun is more than 17 times Earth’s size and nearly 58 times the dimensions of Earth’s volume. 

The cool blue planet, due to the absorption of infrared light by the planet’s Methane atmosphere, comprises a core with the capacity to pick up a lot of gas, making Neptune impossible for the existence of life.

Our Solar system is incomplete without the Moon, a planetary large natural object that travels around the Earth. However, the Moon does not make its light but it reflects the light of the sunlight. 

The total number of moons in our Solar system is 290, out of which one Moon belongs to Earth, two to Mars, 27 to Uranus, 95 to Jupiter, 146 to Saturn, 5 to dwarf planet Pluto, and 14 to Neptune.

The solar system consists of the Sun, terrestrial planets, gas giants, Earth’s Moon, celestial bodies , and various other objects. The unique formation and dynamics continue to amaze scientists offering a glimpse into the vastness and beauty of our cosmic neighbourhood.

The universe consists of more than 500 solar systems as of now or as of our limited knowledge on the universe. Our solar system is present inside the Milkyway galaxy.  The Milkyway galaxy is called so because the Romans named it as they found the earth’s skyline at night to resemble that of a band and a patch of milk. The solar system is the most important part of our Milkyway galaxy. According to experts and astronomers, the solar system is the only planetary body in the universe that supports life. And earth, a part of the solar system, is the only planet that supports life in the universe. But this can easily be false since man has not discovered all the aspects of our universe.

Solar systems consist of eight planets, which are Mercury, Venus, Mars, Earth, Jupiter, Saturn, Uranus and Neptune. Pluto was also a planet but it was derecognized a few years ago because of its size. The main criteria for being a planet are it should orbit around the sun, it should have sufficient mass to assume hydrostatic equilibrium and it should have a clearly defined neighborhood around its orbit. Pluto failed in the second criterion. But Pluto is known as a dwarf planet. All these decisions of naming, recognizing and derecognizing of planetary objects are taken by the International Astronomical Union (IAU). Basically, IAU is an international body that consists of astronomers and scientists all across the world with the main objective and goal of promoting and safeguarding the astronomical sciences in every sphere, through collective international cooperation.

Each planet present in the solar systems revolves around the sun inside their own orbits at their own speed. This is an essential criterion to be declared as a planet in the solar system.

Each of the planets that we mentioned has its own characteristics, which is given below

Characteristics of the Planets in the Solar System

• Mercury: Mercury also knows as the swift planet, is the smallest, hottest and the closet planet to the sun in the solar system.

An essay differs from other writing because it is more structured and it provides the author with their own perspective. In this particular essay, we shall know in detail about the solar system. Use this essay as a reference essay and try writing an essay on the solar system.

Let us begin our learning!

Essay on Solar System

The solar system consists of the sun, eight planets, and sixty-seven satellites of the planets, and a large number of small bodies (comets and asteroids). Earlier, Pluto was considered the smallest planet but now Pluto is not recognized anymore as a planet. The inner solar system comprises Sun, Mercury, Venus, Earth, and Mars. Jupiter, Saturn, Uranus, and Neptune form the outer solar system. These four planets are massive in size; hence they are called Giant Planets. Each planet revolves around the sun in its own orbits at its own speed.

Let us explore all the celestial bodies present in the Solar system.

The Sun was born 4.6 billions of years ago and it was formed from a giant rotating cloud of gasses and dust known as solar Nebula. The sun is the biggest star present at the center of the solar system. It is a self-luminous sphere of gasses. Its gravitational force holds the entire solar system. It has a radius of 695,508 kilometers and is 150 million kilometers away from Earth.

Mercury is the smallest and closest planet to the sun. It is also called Swift planet because it completes its revolution in 88 earth days. Its diameter is only one third of Earth but its density is about the same. The temperature of this planet is as high as 450 degrees Celsius in the mornings and nights are freezing cold. The surface of this planet is filled with craters, mountains and valleys.

Venus is the second closest planet to the sun and the hottest. Venus is the brightest planet and hence called the morning star. Venus is named after the Roman Goddess of love and beauty. Venus completes one revolution around the sun in 255 earth days. Venus spins clockwise on its orbits unlike other planets. Its surface is covered with clouds, craters, mountains and lava plains.

The third planet in the solar system is Earth. This is the only planet that sustains life. It is called the Blue planet because 70% of the earth's surface is covered with water. Earth takes 365 days to complete one revolution around the sun. This planet has only one natural satellite, the Moon.

The fourth planet from the sun in the solar system is Mars. It appears as a red-orange ball because of the presence of iron oxide and so it is called the Red planet. It is the second smallest planet after Mercury. Mars is named after the Roman God of war. Its surface is covered with volcanoes, craters all over.

Jupiter is the largest planet in the solar system. Jupiter is rich in hydrogen and helium gas and so it is also called a Gas Giant planet. Jupiter takes 4333 earth days to complete one revolution around the sun. This planet has 79 satellites. Jupiter has four rings.

Saturn is the least dense planet in the solar system. It is the second-largest planet. Saturn can float in water because it is made up of gasses like helium. The beautiful rings around the planet are made up of bits of ice, rock, and dust. Saturn revolves very slowly around the sun. This planet is named after the Roman God of agriculture and wealth.

Uranus is the coldest planet in the solar system. It takes 84 earth years to complete one revolution around the sun. Uranus is called an ice giant planet because its layer is made of ice and hydrogen, helium and methane. Uranus looks blue in color because of the presence of methane. Uranus has 27 satellites.

Neptune is the eighth and the farthest planet from the sun in the solar system. Neptune is named after the Roman God of the sea. Its atmosphere is made up of hydrogen, helium and methane and the presence of methane gives the color blue to the planet. It takes 165 earth years to complete one revolution. Neptune has 6 rings.

Comets and Asteroids:

Comets and Asteroids are the small celestial bodies that rotate around the sun. Asteroids are made up of rocks, metals and water. Comets are made up of frozen ammonia, methane and small amounts of rocky material.

250 Words Essay on Solar System

The marvel of the solar system.

The Solar System, a celestial marvel, is a complex and fascinating subject. It’s a stellar neighborhood comprising the Sun, eight planets, their moons, and a myriad of smaller objects like asteroids, meteoroids, and comets.

The Sun: The System’s Heart

The Sun, our Solar System’s heart, is an average-sized star, making up 99.86% of the system’s mass. Its immense gravitational pull keeps all the planets in their orbits. The Sun is a fusion reactor, converting hydrogen into helium, releasing energy that sustains life on Earth.

The Planetary Bodies

The planets, ordered from the sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The inner planets, also known as terrestrial planets, are rocky, while the outer planets, the gas giants, are predominantly composed of hydrogen and helium.

The Earth: A Unique Planet

Earth, the third planet from the Sun, is unique because of its ability to support life. Its distance from the Sun, the magnetic field, and the atmosphere create a life-sustaining environment.

Asteroids, Comets, and Dwarf Planets

Beyond Neptune lies the Kuiper Belt, home to icy bodies and dwarf planets like Pluto. The Asteroid Belt, located between Mars and Jupiter, contains numerous small, irregularly shaped bodies.

The Solar System’s Significance

500 words essay on solar system, the solar system: an overview.

The Solar System is a cosmic spectacle that has fascinated astronomers and common folk alike for millennia. It consists of eight planets, numerous moons, asteroids, comets, and dwarf planets, all revolving around the sun, which is the central star.

The Sun: The Central Star

At the core of our Solar System is the Sun. It is a medium-sized star, composed primarily of hydrogen and helium. It generates energy through a process called nuclear fusion, where hydrogen atoms combine to form helium, releasing vast amounts of energy. The Sun’s gravity holds the Solar System together, dictating the orbits of the celestial bodies within it.

The Inner Solar System

The outer solar system, the asteroid belt and dwarf planets.

Between Mars and Jupiter lies the Asteroid Belt, a region populated by millions of asteroids. These rocky remnants are thought to be leftover building blocks of the Solar System. Beyond Neptune’s orbit reside the dwarf planets, the most famous of which is Pluto. Dwarf planets are similar to regular planets but are unable to clear their orbits of other debris.

The Oort Cloud and Kuiper Belt

Exploration and future studies.

In conclusion, our Solar System is a complex and fascinating subject of study. It provides not only a deeper understanding of our place in the universe but also insights into the fundamental processes that govern the cosmos. As we continue to explore and learn, we come closer to answering some of the most profound questions about our existence and the nature of the universe itself.

That’s it! I hope the essay helped you.

Our Solar System: Facts

Our solar system is made up of a star, eight planets, and countless smaller bodies such as dwarf planets, asteroids, and comets.

10 ThingS ABOUT OUR SOLAR SYSTEM

1. Our planetary system is called “the solar system” because we use the word “solar” to describe things related to our star, after the Latin word for Sun, "solis."

2. Our solar system orbits the center of the Milky Way galaxy at about 515,000 mph (828,000 kph). We’re in one of the galaxy’s four spiral arms.

3. It takes our solar system about 230 million years to complete one orbit around the galactic center.

4. There are three general kinds of galaxies: elliptical, spiral, and irregular. The Milky Way is a spiral galaxy.

5. Our solar system is a region of space. It has no atmosphere. But it contains many worlds – including Earth – with many kinds of atmospheres.

6. The planets of our solar system – and even many asteroids – hold hundreds of moons in their orbits.

7. The four giant planets – and at least one asteroid – have rings. None are as spectacular as Saturn’s gorgeous rings.

8. More than 300 robotic spacecraft from many nations have explored destinations beyond Earth's orbit.

9. Our solar system is the only one known to support life. So far, we only know of life on Earth, but we’re looking for more everywhere we can.

10. NASA’s Voyager 1 and Voyager 2 are the only spacecraft leaving our solar system. Three other spacecraft – Pioneer 10, Pioneer 11, and New Horizons – will eventually hit interstellar space.

Size and Distance

Our solar system extends much farther than the planets that orbit the Sun. The solar system also includes the Kuiper Belt that lies past Neptune's orbit. This is a sparsely occupied ring of icy bodies, almost all smaller than the most popular Kuiper Belt Object – dwarf planet Pluto .

Beyond the fringes of the Kuiper Belt is the Oort Cloud . This giant spherical shell surrounds our solar system. It has never been directly observed, but its existence is predicted based on mathematical models and observations of comets that likely originate there.

The Oort Cloud is made of icy pieces of space debris - some bigger than mountains – orbiting our Sun as far as 1.6 light-years away. This shell of material is thick, extending from 5,000 astronomical units to 100,000 astronomical units. One astronomical unit (or AU) is the distance from the Sun to Earth, or about 93 million miles (150 million kilometers).

The Oort Cloud is the boundary of the Sun's gravitational influence, where orbiting objects can turn around and return closer to our Sun.

The Sun's heliosphere doesn't extend quite as far. The heliosphere is the bubble created by the solar wind – a stream of electrically charged gas blowing outward from the Sun in all directions. The boundary where the solar wind is abruptly slowed by pressure from interstellar gases is called the termination shock. This edge occurs between 80-100 astronomical units.

Two NASA spacecraft launched in 1977 have crossed the termination shock: Voyager 1 in 2004 and Voyager 2 in 2007. Voyager 1 went interstellar in 2012 and Voyager 2 joined it in 2018. But it will be many thousands of years before the two Voyagers exit the Oort Cloud.

According to the  NASA/JPL Solar System Dynamics  team, the current tally of moons orbiting planets in our solar system is 293: One moon for Earth; two for Mars; 95 at Jupiter; 146 at Saturn; 28 at Uranus; 16 at Neptune; and five for dwarf planet Pluto.

Astronomers also have documented more than 470 satellites, or moons, orbiting smaller objects, such as asteroids, dwarf planets, or Kuiper Belt Objects (KBOs) beyond the orbit of Neptune. These moons are called s mall-body satellites .

Of the eight planets, Mercury and Venus are the only ones with no moons, although Venus does have a quasi-satellite that has  officially been named Zoozve . 

The giant planets Jupiter and Saturn lead our solar system’s moon counts. In some ways, the swarms of moons around these worlds resemble mini versions of our solar system.

Pluto, smaller than our own moon, has five moons in its orbit, including Charon, a moon so large it makes Pluto wobble.

Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.

At the center, gravity pulled more and more material in. Eventually, the pressure in the core was so great that hydrogen atoms began to combine and form helium, releasing a tremendous amount of energy. With that, our Sun was born, and it eventually amassed more than 99% of the available matter.

Matter farther out in the disk was also clumping together. These clumps smashed into one another, forming larger and larger objects. Some of them grew big enough for their gravity to shape them into spheres, becoming planets, dwarf planets, and large moons. In other cases, planets did not form: the asteroid belt is made of bits and pieces of the early solar system that could never quite come together into a planet. Other smaller leftover pieces became asteroids, comets, meteoroids, and small, irregular moons.

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets. They are all small with solid, rocky surfaces.

Meanwhile, materials we are used to seeing as ice, liquid, or gas settled in the outer regions of the young solar system. Gravity pulled these materials together, and that is where we find gas giants Jupiter and Saturn, and the ice giants Uranus and Neptune.

What is the solar system?

The solar system comprises 8 planets , approximately 170 natural planetary satellites (moons), and countless asteroids , meteorites , and comets .

There are eight planets in the solar system. The four inner terrestrial planets are Mercury , Venus , Earth , and Mars , all of which consist mainly of rock. The four outer planets are Jupiter , Saturn , Neptune , and Uranus , giant planets that consist mainly of either gases or ice. Pluto was considered the ninth planet until 2006, when the International Astronomical Union voted to classify Pluto as a dwarf planet instead.

Where is the solar system?

The solar system is situated within the Orion-Cygnus Arm of the Milky Way Galaxy . Alpha Centauri , made up of the stars Proxima Centauri, Alpha Centauri A, and Alpha Centauri B, is the closest star system to the solar system.

Scientists have multiple theories that explain how the solar system formed. The favoured theory proposes that the solar system formed from a solar nebula , where the Sun was born out of a concentration of kinetic energy and heat at the centre, while debris rotating the nebula collided to create the planets .

Is there life in the solar system aside from on Earth?

Europa and Enceladus , moons of Jupiter and Saturn respectively, are ice-covered rocky objects that scientists think may harbour life in the water beneath the surface. Some geological evidence points to the possibility of microorganisms on Mars .

Recent News

solar system , assemblage consisting of the Sun —an average star in the Milky Way Galaxy —and those bodies orbiting around it: 8 (formerly 9) planets with more than 210 known planetary satellites (moons); many asteroids , some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and dust known as the interplanetary medium . The solar system is part of the " observable universe ," the region of space that humans can actually or theoretically observe with the aid of technology. Unlike the observable universe, the universe is possibly infinite .

The Sun, Moon , and brightest planets were visible to the naked eyes of ancient astronomers, and their observations and calculations of the movements of these bodies gave rise to the science of astronomy . Today the amount of information on the motions, properties, and compositions of the planets and smaller bodies has grown to immense proportions, and the range of observational instruments has extended far beyond the solar system to other galaxies and the edge of the known universe. Yet the solar system and its immediate outer boundary still represent the limit of our physical reach, and they remain the core of our theoretical understanding of the cosmos as well. Earth -launched space probes and landers have gathered data on planets, moons, asteroids, and other bodies, and this data has been added to the measurements collected with telescopes and other instruments from below and above Earth’s atmosphere and to the information extracted from meteorites and from Moon rocks returned by astronauts. All this information is scrutinized in attempts to understand in detail the origin and evolution of the solar system—a goal toward which astronomers continue to make great strides.

Composition of the solar system

Located at the centre of the solar system and influencing the motion of all the other bodies through its gravitational force is the Sun , which in itself contains more than 99 percent of the mass of the system. The planets, in order of their distance outward from the Sun, are Mercury , Venus , Earth , Mars , Jupiter , Saturn , Uranus , and Neptune . Four planets—Jupiter through Neptune—have ring systems, and all but Mercury and Venus have one or more moons. Pluto had been officially listed among the planets since it was discovered in 1930 orbiting beyond Neptune, but in 1992 an icy object was discovered still farther from the Sun than Pluto. Many other such discoveries followed, including an object named Eris that appears to be at least as large as Pluto. It became apparent that Pluto was simply one of the larger members of this new group of objects, collectively known as the Kuiper belt . Accordingly, in August 2006 the International Astronomical Union (IAU), the organization charged by the scientific community with classifying astronomical objects, voted to revoke Pluto’s planetary status and place it under a new classification called dwarf planet . For a discussion of that action and of the definition of planet approved by the IAU, see planet .

Any natural solar system object other than the Sun, a planet, a dwarf planet, or a moon is called a small body ; these include asteroids , meteoroids , and comets . Most of the more than one million asteroids, or minor planets, orbit between Mars and Jupiter in a nearly flat ring called the asteroid belt. The myriad fragments of asteroids and other small pieces of solid matter (smaller than a few tens of metres across) that populate interplanetary space are often termed meteoroids to distinguish them from the larger asteroidal bodies.

The solar system’s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud , is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto’s orbit. The other reservoir, the Kuiper belt , is a thick disk-shaped zone whose main concentration extends 30–50 AU from the Sun, beyond the orbit of Neptune but including a portion of the orbit of Pluto. (One astronomical unit is the average distance from Earth to the Sun—about 150 million km [93 million miles].) Just as asteroids can be regarded as rocky debris left over from the formation of the inner planets, Pluto, its moon Charon , Eris, and the myriad other Kuiper belt objects can be seen as surviving representatives of the icy bodies that accreted to form the cores of Neptune and Uranus. As such, Pluto and Charon may also be considered to be very large comet nuclei. The Centaur objects , a population of comet nuclei having diameters as large as 200 km (125 miles), orbit the Sun between Jupiter and Neptune, probably having been gravitationally perturbed inward from the Kuiper belt. The interplanetary medium —an exceedingly tenuous plasma (ionized gas) laced with concentrations of dust particles —extends outward from the Sun to about 123 AU.

The solar system even contains objects from interstellar space that are just passing through. Two such interstellar objects have been observed. ‘Oumuamua had an unusual cigarlike or pancakelike shape and was possibly composed of nitrogen ice. Comet Borisov was much like the comets of the solar system but with a much higher abundance of carbon monoxide .

All the planets and dwarf planets, the rocky asteroids, and the icy bodies in the Kuiper belt move around the Sun in elliptical orbits in the same direction that the Sun rotates. This motion is termed prograde, or direct, motion. Looking down on the system from a vantage point above Earth’s North Pole , an observer would find that all these orbital motions are in a counterclockwise direction. In striking contrast, the comet nuclei in the Oort cloud are in orbits having random directions, corresponding to their spherical distribution around the plane of the planets.

The shape of an object’s orbit is defined in terms of its eccentricity . For a perfectly circular orbit, the eccentricity is 0; with increasing elongation of the orbit’s shape, the eccentricity increases toward a value of 1, the eccentricity of a parabola. Of the eight major planets, Venus and Neptune have the most circular orbits around the Sun, with eccentricities of 0.007 and 0.009, respectively. Mercury, the closest planet, has the highest eccentricity, with 0.21; the dwarf planet Pluto, with 0.25, is even more eccentric . Another defining attribute of an object’s orbit around the Sun is its inclination , which is the angle that it makes with the plane of Earth’s orbit—the ecliptic plane. Again, of the planets, Mercury’s has the greatest inclination, its orbit lying at 7° to the ecliptic; Pluto’s orbit, by comparison, is much more steeply inclined, at 17.1°. The orbits of the small bodies generally have both higher eccentricities and higher inclinations than those of the planets. Some comets from the Oort cloud have inclinations greater than 90°; their motion around the Sun is thus opposite that of the Sun’s rotation, or retrograde.

The cosmos has always fascinated mankind. Its vastness and mysteries have piqued our curiosity for centuries. To comprehend the universe’s grandeur, we must begin with our neighbourhood in space: the solar system. This solar system essay for class 3 and above offers more profound insights into our cosmic home.

What Is the Solar System?

The solar system comprises various celestial bodies held together by the sun’s gravitational pull, which sits at its centre. This dynamic system is located in the  Milky Way galaxy  and spans a distance of billions of miles. The major constituents of the solar system are the sun, eight planets, their moons, and a range of smaller objects like asteroids, comets, and dwarf planets. It is an intricate dance of objects revolving around the sun, each following its unique path and exhibiting individual characteristics.

How Does the Solar System Work?

The sun is the heart of the solar system, a colossal ball of gas undergoing nuclear fusion. It emits immense heat and light, making life possible on Earth. The sun’s gravitational force is so strong that it keeps all the planets and celestial bodies in their orbits.

The planets orbit the sun in elliptical paths. Like Mercury and Venus, those closest to the sun complete their orbits quicker than those farther away, such as  Neptune . The force of gravity also ensures that moons orbit planets. For example, our Earth has one moon, while Jupiter boasts 79 known moons!

The balance of gravity and the momentum of celestial objects keep everything in place. Without the sun’s gravitational pull, planets would drift away into the vastness of space.

Celestial Bodies Exist in the Solar System

Our solar system’s central star provides energy and light that drive life on Earth.

There are eight in total. The inner planets (Mercury, Venus, Earth, and Mars) are rocky, while the outer planets (Jupiter, Saturn, Uranus, and Neptune) are gas giants or ice giants.

Natural satellites that orbit planets. Their number varies from planet to planet.

4. Asteroids

Rocky fragments remain from the formation of the solar system. Most are found in the asteroid belt between Mars and Jupiter.

Comets are icy bodies that come from the solar system’s outer regions. When they approach the sun, they develop glowing tails.

6. Dwarf Planets

These celestial bodies orbit the sun and have enough mass for their self-gravity to overcome rigid body forces  (2) . However, they still need to clear their neighbouring region of other objects. Pluto  is the most famous dwarf planet.

7. Kuiper Belt & Oort Cloud

These are regions beyond Neptune filled with millions of icy objects. The Kuiper Belt is closer than the Oort Cloud and is the birthplace of short-term comets  (1) .

Our solar system is breathtakingly vast and dynamic, filled with various celestial bodies. Its complex mechanisms and operations provide invaluable insights into the universe’s workings. Understanding the solar system is not just a part of the curriculum for students in class 3 and above; it is a journey into the wondrous realm of space. This essay aims to be a guide, igniting young minds’ curiosity and exploration.

Through the essay on the solar system, your child will gain a foundational understanding of our cosmic neighbourhood, grasping the vastness and intricacies of space. Beyond mere facts, the essay fosters curiosity, inspiring them to dig deeper into the mysteries of the universe and comprehend the grandeur and significance of the celestial dance above us.

1. Where is the solar system situated?

The solar system is in the Milky Way galaxy, in one of its spiral arms called the Orion Arm.

2. How many total solar systems exist?

Numerous solar systems exist, with billions believed to reside in our Milky Way galaxy alone. This showcases the vast expanse and diversity of solar systems.

The solar system’s myriad celestial bodies and dynamic interplays provide a window into the cosmos’s infinite wonders. Understanding and appreciating its grandeur satiates our innate curiosity and helps us find our humble place within the vast tapestry of the universe.

The Shape of The Solar System Has Changed Dramatically, Scientists Say

The shape of the Solar System was once a little more on the doughy side.

Before it arranged itself into a flattened disk, the distribution of dust and rocks had more in common with a donut than a pancake. This is the conclusion scientists reached after studying iron meteorites from the outer Solar System, finding that they can only be explained if the Solar System's shape was once toroidal.

This is information that can help us interpret other emerging planetary systems and determine the order in which they assemble.

The formation of a planetary system around a star starts in a molecular cloud of gas and dust drifting through space. If a portion of the cloud becomes dense enough, it will collapse under its own gravity, spinning as it goes, becoming the seed of a growing baby star . As it spins, the material in the surrounding cloud pulls into a circling disk that feeds into the protostar.

Within that disk smaller clumps form, becoming protoplanetary seeds that either continue to grow into full planets, or – what seems far more frequent – have their development arrested, remaining as a smaller object like an asteroid .

We've seen these disks time and again around other stars , with gaps carved by planets slurping up the dust as they go.

But iron meteorites found here in our own Solar System tell another part of the story.

According to a team led by planetary scientist Bidong Zhang of the University of California Los Angeles, the composition of asteroids in the outer Solar System requires the cloud of material to be donut-shaped, rather than a series of concentric rings in a flat disk. This suggests that the first stages of the system's coalescence are toroidal.

The iron meteorites in question – chunks of rock that have made their long way to Earth from the outer Solar System – are richer in refractory metals than those found in the inner Solar System. These are metals such as platinum and iridium, whose formation can only take place in a very hot environment such as one close to a forming star.

This poses a bit of a pickle, because those meteorites came not from the inner Solar System, but the outer, which means they must have formed close to the Sun and moved outward as the protoplanetary disk expanded. According to modeling conducted by Zhang and his colleagues, though, these iron objects would not have been able to traverse gaps in a protoplanetary disk.

According to their calculations, the migration could have occurred most easily if the protoplanetary structure was toroidal in shape. This would have ushered the metal-rich objects towards the outer fringes of the forming Solar System.

Then, as the disk cooled and the planets started to form, the inability of rocks to travel across gaps in the disk would have acted as a very effective fence, keeping them from migrating back towards the Sun under the pull of gravity.

"Once Jupiter formed, it very likely opened a physical gap that trapped the iridium and platinum metals in the outer disk and prevented them from falling into the Sun," Zhang says .

"These metals were later incorporated into asteroids that formed in the outer disk. This explains why meteorites formed in the outer disk – carbonaceous chondrites and carbonaceous-type iron meteorites – have much higher iridium and platinum contents than their inner-disk peers."

It's amazing what you can learn from a lump of pitted, metallic rock.

The research has been published in the Proceedings of the National Academy of Sciences .

Why do some planets have moons and some don’t? – Siddharth, age 6, Texas

On Earth, you can look up at night and see the Moon shining bright from hundreds of thousands of miles away. But if you went to Venus, that wouldn’t be the case. Not every planet has a moon – so why do some planets have several moons, while others have none?

I’m a physics instructor who has followed the current theories that describe why some planets have moons and some don’t.

First, a moon is called a natural satellite. Astronomers refer to satellites as objects in space that orbit larger bodies. Since a moon isn’t human-made, it’s a natural satellite.

Currently, there are two main theories for why some planets have moons. Moons are either gravitationally captured if they are within what’s called a planet’s Hill sphere radius , or they’re formed along with a solar system.

The Hill sphere radius

Objects exert a gravitational force of attraction on other nearby objects. The larger the object is, the greater the force of attraction.

This gravitational force is the reason we all stay grounded to Earth instead of floating away.

The solar system is dominated by the Sun’s large gravitational force, which keeps all of the planets in orbit. The Sun is the most massive object in our solar system, which means it has the most gravitational influence on objects such as planets.

In order for a satellite to orbit a planet, it has to be close enough for the planet to exert enough force to keep it in orbit. The minimum distance for a planet to keep a satellite in orbit is called the Hill sphere radius .

The Hill sphere radius is based on the mass of both the larger object and the smaller object. The Moon orbiting Earth is a good example of how the Hill sphere radius works. The Earth orbits around the Sun, but the Moon is close enough to Earth that Earth’s gravitational pull captures it. The moon orbits around the Earth, rather than the Sun, because it is within Earth’s Hill sphere radius.

Smaller planets like Mercury have a tiny Hill sphere radius, since they can’t exert a large gravitational pull. Any potential moons would likely get pulled in by the Sun instead.

Many scientists are still looking to see whether these planets may have had small moons in the past. Back during the formation of the solar system, they may have had moons that got knocked away by collisions with other space objects.

Mars has two moons, Phobos and Deimos. Scientists still debate whether these came from asteroids that passed close into Mars’ Hill sphere radius and got captured by the planet, or if they were formed at the same time as the solar system. More evidence supports the first theory , because Mars is close to the asteroid belt.

Jupiter, Saturn, Uranus and Neptune have larger Hill sphere radii, because they are much larger than Earth, Mars, Mercury and Venus and they’re farther from the Sun. Their gravitational pulls can attract and keep more natural satellites such as moons in orbit. For example, Jupiter has 95 moons , while Saturn has 146 .

Moons forming with a solar system

Another theory suggests that some moons formed at the same time as their solar system.

Solar systems start out with a big disk of gas rotating around a sun. As the gas rotates around the sun, it condenses into planets and moons that rotate around them . The planets and moons then all rotate in the same direction.

But only a few moons in our solar system were likely created this way. Scientists predict that Jupiter’s and Saturn’s inner moons formed during the emergence of our solar system because they’re so old. The rest of the moons in our solar system, including Jupiter’s and Saturn’s outer moons, were probably gravitationally captured by their planets.

Earth’s Moon is special because it likely formed in a different way. Scientists believe that long ago, a large, Mars-sized object collided with the Earth. During that collision, a big chunk flew off the Earth and into its orbit and became the Moon.

Scientists guess that the Moon formed this way because they’ve found a type of rock called basalt in soil on the Moon’s surface. The Moon’s basalt looks the same as basalt found inside the Earth.

Ultimately, the question of why some planets have moons is still widely debated, but factors such as a planet’s size, gravitational pull, Hill sphere radius and how its solar system formed may play a role.

NASA’s New Horizons spacecraft is hurtling out of the solar system at an incredible speed. It is currently about 8 billion kilometres from the sun, and by the time you finish reading this story, it will have sped thousands of kilometres further into the frigid gloom. It is lonely out there. Even the giant planet Jupiter is but a tiny speck.

New Horizons is mainly known for giving us our first proper look at the dwarf planet Pluto in 2015. Until then, we had only seen it as a blurry smudge. It has also taught us much about the solar system’s outer reaches and the small, frozen worlds that float there. “It’s really been an Alice in Wonderland kind of story,” says Alan Stern, the principal investigator of the mission. “It’s been dreamlike and we’ve discovered wonderful things.”

Is there an ancient black hole at the edge of the solar system?

However, the dream isn’t over yet because New Horizons may be poised for a surprise final act. In early 2024, one of its detectors recorded an unexpected uptick in the amount of dust it was encountering. Since that material could have been created in collisions between rock fragments, astronomers now wonder if there are many objects beyond the rubble-strewn Kuiper belt often considered the edge of the solar system. If so, our system’s boundaries will need to be redrawn and our models of how it formed thrown into doubt.

Stern and his colleagues are obviously keen to take advantage of their probe’s unique position to learn more about this unexplored wilderness while they still can. “It’s an…

• The exponential growth of solar power will change the world

An energy-rich future is within reach

Your browser does not support the <audio> element.

I t is 70 years since AT&T ’s Bell Labs unveiled a new technology for turning sunlight into power. The phone company hoped it could replace the batteries that run equipment in out-of-the-way places. It also realised that powering devices with light alone showed how science could make the future seem wonderful; hence a press event at which sunshine kept a toy Ferris wheel spinning round and round.

Today solar power is long past the toy phase. Panels now occupy an area around half that of Wales, and this year they will provide the world with about 6% of its electricity—which is almost three times as much electrical energy as America consumed back in 1954. Yet this historic growth is only the second-most-remarkable thing about the rise of solar power. The most remarkable is that it is nowhere near over.

To call solar power’s rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the world’s entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.

Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s. By the 2040s they may be the largest source not just of electricity but of all energy. On current trends, the all-in cost of the electricity they produce promises to be less than half as expensive as the cheapest available today. This will not stop climate change, but could slow it a lot faster. Much of the world—including Africa , where 600m people still cannot light their homes—will begin to feel energy-rich. That feeling will be a new and transformational one for humankind.

To grasp that this is not some environmentalist fever dream, consider solar economics. As the cumulative production of a manufactured good increases, costs go down. As costs go down, demand goes up. As demand goes up, production increases—and costs go down further. This cannot go on for ever; production, demand or both always become constrained. In earlier energy transitions—from wood to coal, coal to oil or oil to gas—the efficiency of extraction grew, but it was eventually offset by the cost of finding ever more fuel.

As our essay this week explains, solar power faces no such constraint. The resources needed to produce solar cells and plant them on solar farms are silicon-rich sand, sunny places and human ingenuity, all three of which are abundant. Making cells also takes energy, but solar power is fast making that abundant, too. As for demand, it is both huge and elastic—if you make electricity cheaper, people will find uses for it. The result is that, in contrast to earlier energy sources, solar power has routinely become cheaper and will continue to do so.

Other constraints do exist. Given people’s proclivity for living outside daylight hours, solar power needs to be complemented with storage and supplemented by other technologies. Heavy industry and aviation and freight have been hard to electrify. Fortunately, these problems may be solved as batteries and fuels created by electrolysis gradually become cheaper.

Another worry is that the vast majority of the world’s solar panels, and almost all the purified silicon from which they are made, come from China. Its solar industry is highly competitive, heavily subsidised and is outstripping current demand—quite an achievement given all the solar capacity China is installing within its own borders. This means that Chinese capacity is big enough to keep the expansion going for years to come, even if some of the companies involved go to the wall and some investment dries up.

In the long run, a world in which more energy is generated without the oil and gas that come from unstable or unfriendly parts of the world will be more dependable. Still, although the Chinese Communist Party cannot rig the price of sunlight as OPEC tries to rig that of oil, the fact that a vital industry resides in a single hostile country is worrying.

It is a concern that America feels keenly, which is why it has put tariffs on Chinese solar equipment. However, because almost all the demand for solar panels still lies in the future, the rest of the world will have plenty of scope to get into the market. America’s adoption of solar energy could be frustrated by a pro-fossil-fuel Trump presidency, but only temporarily and painfully. It could equally be enhanced if America released pent up demand, by making it easier to install panels on homes and to join the grid—the country has a terawatt of new solar capacity waiting to be connected. Carbon prices would help, just as they did in the switch from coal to gas in the European Union.

The aim should be for the virtuous circle of solar-power production to turn as fast as possible. That is because it offers the prize of cheaper energy. The benefits start with a boost to productivity. Anything that people use energy for today will cost less—and that includes pretty much everything. Then come the things cheap energy will make possible. People who could never afford to will start lighting their houses or driving a car. Cheap energy can purify water, and even desalinate it. It can drive the hungry machinery of artificial intelligence. It can make billions of homes and offices more bearable in summers that will, for decades to come, be getting hotter.

But it is the things that nobody has yet thought of that will be most consequential. In its radical abundance, cheaper energy will free the imagination, setting tiny Ferris wheels of the mind spinning with excitement and new possibilities.

This week marks the summer solstice in the northern hemisphere. The Sun rising to its highest point in the sky will in decades to come shine down on a world where nobody need go without the blessings of electricity and where the access to energy invigorates all those it touches. ■
