|Discovered by||Audouin Dollfus|
|Discovery date||15 December 1966|
Janus is a moon of Saturn. It was discovered by Audouin Dollfus in 1966. Astronomers were first mistaken that another moon, Epimetheus, was the same as Janus. Voyager 1 confirmed in 1980 that there were two moons that share the same orbit.
Janus is named after the two-faced Roman god Janus. Although the name was informally proposed soon after the initial 1966 discovery, it was not officially adopted until 1983, when Epimetheus was also named. It is also known as Saturn X
