What is a Solar System

Ever thought where this only planet having life i.e our earth exists? Where do the sun, moon, and other planets exist? What are these heavenly bodies made up of? How do they revolve or rotate? How many such bodies exist. What is the galaxy? Have ever these questions crossed your mind? Well, here we are going to study our solar system in detail and will try to crack the answers to all the questions related to the solar system. A solar system as the name suggests is an entire system in reference to the sun which means the sun is the most dominant heavenly body or star which regulates the entire system known as the solar system. We will start with the solar system definition.

Solar System Information

A solar system as the name suggests is a system where there is collection or assemblage of many heavenly bodies also called celestial bodies. Because the name is the solar system it gives us the idea that the sun is an important factor in the solar system. Hence, the solar system can also be defined as a collection of planets which are celestial bodies along with their moons which orbit around the sun in a Milkyway galaxy. With these planets, the bodies that go around the sun are comets, asteroids, and meteoroids which are also heavenly bodies like planets. This way we can explain the solar system. Also, let's have a look at a picture of the solar system which will help us understand the whole concept in a much clear way.

What is the Meaning of the Solar System?

Let's describe the solar system.

Solar systems include many heavenly bodies like the sun, satellites, and planets with their moons. Apart from the above-mentioned bodies, there are other bodies also which come together to make solar systems and a universe. A solar system is a monumentally huge system. Its size is around 100 astronomical units which is around 15 trillion km. As we all know that in a solar system all the bodies go round the sun in an orbit around it. This happens because of the immense gravitational pull of the sun which keeps the bodies around it. The planets in the solar system range from small rocky planets to huge gigantic balls of gas and ice. The biggest body or object in the solar system is the sun.

What do you Mean by the Solar System?

A gravitationally bound system consisting of many celestial bodies because of the gravitational force of a huge mass called the sun is referred to as a solar system.

Most of the mass present in the solar system is collectively found in a  huge star called as sun after sun the most amount of solar system's mass is present in the largest known planet which is Jupiter.

What Does the Solar System Consist of?

Below mentioned are the known bodies that are present in the solar system.

  • Planets 

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

  • Stars


  • Dwarf planets

Pluto, Eris, Ceres

  • Comets

  • Minor planets

  • Natural satellites

Members of the Solar System

Let's study the members of this huge solar system in detail:

  • Planets

There are a total of 8 known planets existing in our solar system. These 8 planets are of 2 different types :

Planets made up of rocky material and metal. Such planets made up of solid rocks are Mercury, Venus, Earth, and Mars.

Another type of planets are made up of gases. Gases like methane, hydrogen, and helium. These are large planets far larger than the rocky planets. Such planets are Jupiter, Saturn, Uranus, Neptune.

While rocky planets are small and form the inner circle of the solar system and are also called the terrestrial planets, the larger planets made up of gases are known as giant planets, and these form the outer circle of the solar system. All these planets have orbits that are circular.

  • Asteroids

Asteroids are irregular shaped small rocky objects that prominently are found in the asteroid belt lying in between the Mars and Jupiter orbits. These asteroids are made up of carbon, metal, and rock and are also called as the minor planets. They are named so because they are much smaller than the planets. These asteroids cannot be seen from the earth with the naked eye, however, it is possible sometimes to see them using binoculars or telescopes.

  • Comets

These are small object type material existing in the sole system and are made up of ice. Kuiper belt is a range that is beyond the planet Neptune; it is believed that these comets come from the same area. You must have heard about Halley's comet which appears once in every 76years.

  • Satellites

Those objects which revolve around a planet and are part of a solar system. The best example is the earth's satellite which is the moon.

Satellites can be natural and man-made as well. The man-made satellite revolves around the earth.

  • Dwarf Planets

These are objects found at various places in the solar system. They are larger than the asteroids but smaller than the planets. Ceres is the nearest dwarf planet. Pluto which formerly was a planet but later it was counted as a dwarf planet.

FAQ (Frequently Asked Questions)

Ques) Give some Information About the Solar System.

Ans) Solar System refers to a collection of various heavenly or celestial bodies that orbit the sun and are bound because of the gravitational pull of the sun. The various heavenly bodies which are part of this solar system are planets, asteroids, dwarf planets, satellites, comets. The size of this solar system is monumentally huge. Most of the mass of the solar system is in the sun. Jupiter also contains a huge amount of mass of the solar system.

Ques) What does the Solar System Comprise.

Ans) The solar system comprises many celestial bodies made up of different materials It has 8 planets, asteroids which are irregular shaped rocky objects, comets which are made up of ice, dwarf planets which are smaller than planets but larger than asteroids and satellites which revolve around a planet.
