What is a constellation...
A constellation is a group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure.
The first use for Constellations was probably religious. People thought that the Gods lived in the heavens and that they created them. Many cultures believed that the positions of the stars were their God's way of telling stories. So it seemed natural to recognize patterns in the sky, give them names, and tell stories about them. We inherited the names for our constellations from the Greeks. And they named the constellations after their mythological heroes and legends, and every constellation has a story
