What do you see at night?
Other stars in the galaxy follow their own orbits as well. This stellar motion causes constellations to change their shapes over time, but it takes a long time for people to see those changes. Astronomer Edmond Halley, for example, discovered that stars described in ancient Greek star charts had changed position slightly 1,600 years later. In about 50,000 years, the Big Dipper's shape will have changed so much that it won't look the same as it does today.
