Constellations are stars you can connect to make pictures in the sky. Since ancient times, astronomers have looked at the stars and connected them into meaningful pictures.
These pictures were used to tell myths and stories, and they were also used to help astronomers find their position in the solar system. Today, astronomers think that constellations were invented around three thousand years ago.
Our sky is made up of 88 constellations in total. Depending on the earth's position, different stars are hidden from the earth’s view. Since the earth spins on its axis and rotates around the sun, we face different directions depending on the time of year.
Constellations helped astronomers figure out the earth’s rotation patterns.
