How did Saturn get its name?
The Romans knew of seven bright objects in the sky: the Sun, the Moon, and five brightest planets. They named them after their most important gods. Saturn was named after the Roman god of agriculture. According to myth, Saturn introduced agriculture to his people by teaching them how to farm the land. Saturn was also the Roman god of time and this is perhaps why the slowest (in orbit around the Sun) of the five bright planets was named after him. In Roman mythology, Saturn was the father of Jupiter. Saturday is also named after the Roman god Saturn (Saturn's Day).
