The Earth is the planet you (and everyone else) live on! The Moon is a natural satellite of the Earth. This means it travels around our planet in a huge circle called an 'orbit'. The Sun is a star in the centre of our Solar System.

It's the movements of these objects that give us days, years, and even eclipses! Test your knowledge of these astronomical timescales and events.
