Janus was discovered by A. Dollfus in 1966. Janus is the 5th closest moon to Saturn. Janus is one of the small moons
, and is about the size of a county.
Janus and Epimetheus orbit Saturn together. They are only 50 km (33 miles) apart as they orbit Saturn, which is a little like having two moons in the same city. The fact that they are so close may mean that they are two pieces of what may once have been a single moon.
