What is the solar system?

It is our sun. But it is more than that. It is everything that moves around the sun, too.

We know that eight planets circle our sun. There might be more that we can't see!

Other things orbit the sun, too. Dwarf planets, comets and asteroids orbit the sun. Dust and pieces of ice orbit, too!

The sun is a star. It is the biggest thing found in our solar system. All the light and warmth on the planets come from the sun.
