Epimetheus was discovered by R. Walker in 1966. Epimetheus is the 4th closest moon to Saturn, with a standoff distance of 151,422 km. Epimetheus is one of the small moons
, being 70 x 50 km (45 x 33 miles) in size. Its dimensions make Epimetheus about the size of the city of Los Angeles.
Epimetheus and Janus 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.
As a small moon, the composition and surface features of Epimetheus are unknown.
