4.group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure.

5.galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. We live on a planet called Earth that is part of our solar system. ... A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems.
