The stars have been studied since the beginning of man. "The earliest known efforts to catalog the stars dates back to cuneiform texts and artifacts from 6000 years ago." Most of our current constellations we can attribute to Roman, Greek, and Babylonian mythology. Around the 7th century B.C., in the time of Homer, the stars were thought to replicate animals. By the 5th century B.C. most of the constellations began to be associated with myths. Mythology, of course, influenced the naming of many objects in the night sky, not just the constellations. Planets and moons bear names from mythology.
