Solar System for Kids

The solar system is made by the sun and the planets. Students will learn about the solar system model, the solar system planet, natural satellites of planets, and names of the planets in the solar system. The motive of the discussions is to relate the solar system for kids with the concepts of measuring distance, comparing numbers, comparing and ordering numbers, mathematical operations, and subtraction sums for class 3.

What Is Solar System?

The solar system is the gravitational bond between the sun and the objects orbiting it. It is formed due to the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system’s mass is in the sun itself, and the remaining mass is contained in Jupiter.

Solar System Planet:

The inner system planets are Mercury, Venus, Earth, and Mars. These planets are also called terrestrial planets, primarily made of rock and metal. Also, the inner solar system contains an asteroid belt which can be seen between the orbit of Mars and Jupiter. The other four planets in the outer system are larger and more massive than the terrestrial planets. These planets are

  1. Jupiter,
  2. Saturn,
  3. Uranus and
  4. Neptune.

The gas giants are Jupiter and Saturn, and the ice giants are Uranus and Neptune. All eight planets orbit the sun in a nearly circular orbit that lies on the earth’s orbit plane. Also, dwarf planets orbit the sun, and an uncountable number of small solar system bodies orbit around the sun.

Natural Satellites of Planets:

The planets also have their natural satellite like Moon is the earth’s natural satellite. Similarly, Ganymede is the natural satellite of Jupiter and Titan is a natural satellite of Saturn. Some of the planets have more than one moon.

Solar System Planet in Order:

The planets come in the order starting nearest to farthest to the sun are the following:

  1. Mercury
  2. Venus
  3. Earth
  4. Mars
  5. Jupiter
  6. Saturn
  7. Uranus
  8. Neptune

Extension of the Solar System for Kids:

Scientist estimates that the solar system extends from the sun, and its edge is about 15 billion kilometres from the sun. There are four inner planets before the asteroid belt. There are disk-shaped Kuiper belts far beyond the teardrop-shaped heliopause in the solar system.

The list below concerns the planets’ distance from the sun in the solar system for kids.

Planets’ Distance From the Sun:

Planets’ Distance From the Sun

Subtraction Word Problem:

Question 1:

John and Danny Were Discussing Their Homework. The Teacher Asked Both of Them to Find the Distance Between the First Two Terrestrial Planets From the Chart Given Above. How Will They Find the Distance Between the Planets? Also, Find the Distance.


The first two terrestrial planets are mercury and venus.

The distance of Venus from the Sun is 108 million km and
The length of Mercury from the sun is 57 million km.

So, subtracting the distance of venus and mercury from the sun to
each other, we will get the distance between the planets.

Solar system

So, the distance between Mercury and Venus is
(108 – 57) million km = 51 million km

Question 2:

In the Class, the Teacher Asked Daniel to Find the Distance Between
Two Gas Giants in the Solar System. What Will His Answer Be?


The two gas giants in the solar system are Jupiter and Saturn. Saturn’s distance from the sun is 1437 million km, and the distance of
Jupiter from the sun is 780 million km. The distance between the two gas giants is the difference between their distance from Sun.

Number Operation:

Question 3:

Uncle Harry Was Showing Marry How to Find Half of the Distance
Between the Planet Mars and Jupiter. Find the Process and Also, Find
Half of the Distance Between Them.


The distance between Jupiter from the sun is 780 million km, and the
length of Mars from the sun is 228 million km. So, the distance between Mars and Jupiter is a difference in their
distances from the sun.

Solar system

The distance between Mars and Jupiter is
(780 – 228) million km = 552 million km
So, half of the distance
552 ÷ 2 million km = 276 million km

Question 4:

Ram and Raju Discussed the Distance of One of the Gas Giants, Saturn, From the Sun. Ram Said That the Earth Is Further From the Sun Than Saturn. But Raju Said Saturn Is Further From the Sun Than Our Earth. Whose Statement Is Correct and Who’s Statement Is Wrong? Also, Find the Distance Between Earth and Saturn.


Solar system

Now, 1437 >149
So, Saturn is farther from the sun than earth.

Solar system

The distance of Saturn from the earth is
1437 – 149 = 1288 million km
So, Saturn is 1288 million km far from the earth.

Comparing and Ordering Numbers

Question 5:

An Astronaut Travelled to Both the Ice Giants. Now, He Has to Find Which One of Them Is Closer to the Sun? Also, He Has to Find the Distance Between the Farthest Ice Giant and Our Earth.


The two ice giants in the solar system are Uranus and Neptune.

Solar system

Now, 2871 < 4530
So, Uranus is closer to the sun than Neptune.
Also, Neptune is the farthest ice giant from the earth.

Solar system

The distance of Neptune from the earth is
4530 – 149 = 4381 million km

Question 6:

A Scientist Observed That the Inner System of Our Solar System Ranges Nearly 750 Million Km. This Is Made of Terrestrial Planets and the Asteroid Belt. Scientist Has to Find the Measurement of the Space in the Inner Solar System After the Terrestrial


The total distance of the terrestrial planets from the sun is
57 + 108 + 149 + 228 = 542 million km

Solar system

So, the remaining space is
750 – 542 = 208 million km

Hence, the remaining space after the terrestrial planets in the inner
solar system is 208 million km.
