Dione

One of the larger moons of Saturn, discovered in 1684. It has a diameter of 1,120 km/696 mi and orbits Saturn at an average distance of 377,000 km/234,000 mi, with a period (time taken to circle the planet) of 2.74 days.

The two hemispheres of Dione are quite different. The leading side is heavily cratered, but the trailing side is covered with wispy streaks that may be valleys in the icy surface. It shares the same orbit as a smaller moon, Helene.
