Who discovered the planet Saturn?

It is impossible to determine who discovered Saturn, as it is one of five planets that are visible without the aid of instruments. Saturn has been widely observed by people for thousands of years, although its unique and complex system of rings are only visible using a telescope.

Planets that are visible to the naked eye were of great interest to early astronomers who were curious about their movements across the night sky. The sixth planet from the sun, Saturn was first seen through a telescope by Galileo Galilei, who is credited as being the first to discover Saturn's moon Titan.
