If you draw lines between them (and use lots of imagination!) they sometimes look like objects, animals or people. The ancient Greeks thought that Orion looked like a giant hunter with a sword attached to his belt! 5.__________ As the earth moves around the sun, we see the constellations in different positions in the sky at different times of the year. In the same way, the whole sky seems to move towards the west as the earth rotates on its axis throughout the night.
