Moons : Epimetheus

Saturn Moons : Epimetheus

The cratered surface and irregular shape of Epimetheus is highlighted by dramatic shadows in this composite close-up image from the Cassini spacecraft. Orbiting 91,000 kilometers above Saturn's cloud tops, Epimetheus is not alone.

Saturnian moon Janus occupies an orbit separated from Epimetheus' by only about 50 kilometers. The two actually approach each other once every four years, but instead of colliding, the moons deftly exchange orbits and move apart again!
