Astronomy is the study of celestial objects outside of earth’s atmosphere as well as space and the entire physical universe. Almost every culture has had some form of astronomy and many of the ancient civilizations based daily life decisions on the movement of the planets.
Our advanced technologies now give us the ability to watch, monitor, and explore at even greater depths.

Both the Greek and Roman civilizations believed that all of the planets, except earth, were home to their gods. Due to their limitations, they only named Jupiter, Saturn, Mars, Venus, and Mercury. After the creation of the telescope we could see other planets beyond these four and other names were given at that time.
