Explore the Planets, Moons and Wonders of Space
The Solar System for kids is the group of planets, moons, and other objects that travel around our star, the Sun. It formed about 4.6 billion years ago and is held together by the Sun's powerful gravity.
At the centre of the Solar System, the Sun provides light and heat, making life on Earth possible. Everything in the Solar System, including planets and smaller objects, orbits (moves around) the Sun.
There are eight planets in the Solar System. In order from the Sun, they are:
The first four planets are rocky planets, while the outer planets are gas giants or ice giants made mostly of gases and ice.
The Solar System is not just made of planets. It also includes:
These objects all move through space, following paths controlled by gravity.
Learning about the Solar System for kids helps us understand how our planet fits into space. It teaches us about planets, gravity and how the universe works.
Scientists study the Solar System using telescopes, satellites and space missions to learn more about how it formed and whether life might exist elsewhere.
