Some Space Facts for Kids

Have you ever wondered what is outside the Earth? Is Earth all there is? Are there other planets? Where is the sun found and the moon? All these questions bring you to the topic of outer space!

Outer Space or Space refers to more or less everything outside the Earth's Atmosphere. It begins at a point known as the Kármán Line (100km from Earth) and extends beyond it. Space is also scientifically known as the Universe. The universe contains Galaxies and these galaxies have solar systems, stars, planets, etc within them. Earth is a planet in a galaxy called The Milky Way. Here, we are going to explain space facts for kids, facts about space for kids, and space information for kids.

What is in Outer Space?

While it is easy to imagine outer space as a vast endless black area, space has many objects.

Stars in Space

Stars in Space

Some objects found in outer space include - 

  • Other planets such as Venus, Jupiter 

  • Asteroids such as Ceres 

  • Dwarf planets such as Pluto 

  • Kuiper Belt Objects 

  • Comets 

  • Stars 

  • Black Holes 

Light in Space Facts 

Outer Space is completely dark. It is pitch black. Why so? The reason for that is that there is no air in outer space. Since there is no air outside the Earth's Atmosphere there is no air to scatter sunlight thus no colours can be formed. 

As there is only a vacuum (state of absence of air) in space, even sounds can’t travel. This means that once you reach the outside of the earth's atmosphere everything is completely silent. The lack of air is also one of the reasons why astronauts have to wear special space suits when in outer space. 

Facts About Planets in Space

There are 8 planets in the Solar System. These planets include - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Here are some interesting facts about these planets 

Planets in the Solar System

Planets in the Solar System 

  • Mercury is the closest to the sun and has no atmosphere. Due to the lack of atmosphere, the temperature fluctuates immensely.

  • Venus is the hottest planet and revolves around the sun the fastest. It is also the slowest planet to rotate on its axis

  • Mars is the red planet. It is believed that life could exist on Mars. The asteroid belt is found between Jupiter and Mars. 

  • Jupiter is the largest planet and is called a gas giant because it’s mainly made up of gas. It also has the highest number of moons

  • Saturn has rings surrounding it. These rings are made up of icy rocks 

  • Uranus rotates on its side like a barrel

  • Neptune is considered to be a water planet that has constant storms. These storms have winds that blow 10 times stronger than the hurricanes on earth. 

Information About Space 

  • The Sun is the largest object in our solar system and it is a star. It’s almost 300,000 times the mass of the Earth. 

  • Pluto was previously considered a planet but is now clubbed in with dwarf planets 

  • Beyond Neptune, there is a doughnut-shaped belt of objects that revolve around the sun in an elliptical orbit. This belt is called the Kuiper Belt. It contains dwarf planets, asteroids, etc. They are commonly referred to as Kuiper Belt objects.

  • Comets mostly come from the Kuiper Belt or the Oort Cloud (which extends beyond Kuiper Belt) and revolve around the sun in an elliptical orbit. Halley's Comet is an example of one such comet. 

  • As the Moon has no wind, tire tracks and footsteps left on the moon by astronauts and machines are still intact. 

  • The Moon does not have any light of its own, it reflects the light of the Sun. 

  • The Sun and Moon are responsible for tides on Earth.

  • Space has Black Holes that suck in light. They also have very strong gravitational fields.

  • Everything in Space is constantly moving. The Sun revolves around the centre of the Milky Way as well.

  • Stars are billions of light years away from us. 

  • A dog named Laika has been to space in a Russian spacecraft called Sputnik 2 in the year 1957!


Outer Space refers to everything outside the Earth's Atmosphere. It consists of planets, stars, asteroids, comets, black holes, galaxies, etc. The Earth is a part of the Solar System. The Solar System includes The Sun and the 8 planets. It also includes the asteroid belt and Kuiper Belt (which contains Dwarf Planets). As there is only a vacuum in space and no air, sound and light can’t travel. This means that outer space is completely dark and quiet. Thus, we have discussed light in space facts and information about space in detail.

FAQs on Amazing Facts about Space for Kids

1. What is the difference between a comet and an asteroid?

A comet is a relatively small body that orbits the sun in an elliptical orbit. They are usually found in the Oort Cloud and the Kuiper Belt. When they come close to the sun they appear shiny and can appear to have a tail when seen from Earth. An Asteroid is a rocky, airless body that orbits the sun. They are remnants from the time of planet formation and are mostly found in the Asteroid Belt between Jupiter and Mars. 

2. What is a black hole?

A Black Hole isn’t like a planet or a star. It does not have a surface area or emits light. It is essentially an area where matter collapses in on itself. They have a very strong gravitational pull. Even light can't escape its gravitational pull. As they suck in light, they can’t be photographed or seen but their existence is confirmed by the disks of material surrounding them which give them a whirlpool-like appearance. They are formed when very big stars die or explode.

3. What is the difference between a meteor, a meteorite, and a meteoroid?

All three are different forms of Asteroids. A meteoroid is a body of rock or space debris. They are smaller than asteroids. A meteor is an asteroid that enters the Earth’s atmosphere and burns up creating a streak of light visible in the night sky. They are commonly called shooting stars. A meteorite is an asteroid that crosses Earth’s atmosphere and reaches its surface.
