Captured by NASA’s Cassini spacecraft, Dione reveals its surface created by tectonics and impact cratering.
Dione is a moon of Saturn. At 698 miles or 1,123 kilometers across, Dione is the 15th largest moon in the Solar System. Tectonic features tell the story of how Dione has been heated and cooled since its formation and impact craters have changed its topography over its history.
Dione’s icy surface includes heavily cratered terrain, moderately cratered plains, lightly cratered plains, and areas of tectonic fractures.
The image was obtained at a distance of approximately 68,000 miles looking toward the trailing hemisphere of Dione.
