Earth, Sun and Moon

The Earth is the planet you (and everyone else) lives on. Like other planets, it is spherical like a ball. Although long ago, some people thought the Earth was flat!

The Moon is a natural satellite of the Earth. This means it travels around our planet in a huge circle called an 'orbit'. The Moon is the only natural place in space humans have ever visited! We can often see the Moon on a clear night. Have you noticed you can sometimes see it in the day too?

Both the Earth and Moon orbit the Sun. The Sun is a star in the centre of our Solar System. The Sun provides the light and heat you experience during the daytime. This energy keeps all things on Earth alive. The Sun is massive - over one million Earths could fit inside it!

Have you noticed there are four seasons each year? Spring, Summer, Autumn and Winter. This is because the Earth travels around the Sun once a year on a tilt.

Did you know we get day and night because the Earth spins on its axis!
