What is Dione?
Mythology Behind Dione's Name
Features and Orbit
Dione's surface is mainly ice. As you will see in pictures, it has lots of craters and there are wispy streaks on the surface. Scientists believe that the craters were made by meteorites. Some of these craters are as large as 62 miles (100 km) across and are one of the most common terrain features. The streaks are large fractures in the ice.
Dione makes a complete orbit of Dione every 2.74 days. It also shares and orbit with 2 smaller moons, Helene and Polyceuces. But unlike the Earth's moon, Dione does not go through different phases. One side constantly faces Saturn. Dione also slightly speeds up at it approaches another moon and slows down as is draws away from them.
