Discovery of Epimetheus Moon

Date: December 18, 1966 • Location: Rome, Italy

Epimetheus, one of the moons of Saturn, was discovered, but was mistaken for Janus; it took twelve years to determine that they are two distinct objects sharing the same orbit.

Epimetheus is an inner satellite of Saturn. It is named after the titan Epimetheus, the brother of Prometheus and son of Iapetus.
