Can you create your own solar system art? You can use any materials you like. Perhaps you might like to paint, or use pens or chalk? You could cut out pictures from a magazine or even make art using items around the house to make 3D art!
Look at the planets closely; they are different colours and sizes. Saturn has a ring around it too. Try to make your picture show these differences.
I can wait to see how inventive you have been.
