What are the differences between a galaxy and a constellation?

This is my physics homework. Please helpWhat are the differences between a galaxy and a constellation?A galaxy is a system of stars all circling a specific spot in the center of that galaxy.



A constellation is just a group of stars that people have used to draw pictures in the sky with. These stars may or may not even be related to each other in actual space, but are grouped together solely because they look relatively close to each other in our night sky.What are the differences between a galaxy and a constellation?A constellation is an apparent cluster of stars,while a galaxy is a real cluster of stars, i.e., a bunch of stars that actually are close together.
