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.

The word nebula is used to talk about any dusty, fuzzy objects in space but they can be very different things! Can you classify each image into its proper category?
