Dione on the Edge

Saturn’s moon Dione drifts before the planet’s rings, seen here almost edge on. For all their immense width, the rings are relatively paper-thin, about 30 feet (10 meters) in most places. For its part, Dione is about 698 miles (1,123 kilometers) across.

This natural-color view was obtained on Aug. 17, 2015 with Cassini’s wide-angle camera at a distance of approximately 66,200 miles (106,500 kilometers) from Dione.
The Cassini spacecraft ended its mission on Sept. 15, 2017.

New gravity data from recent Cassini flybys of the giant planet suggest that Dione's crust floats on an ocean 62 miles below the surface, and may harbor microbial life.
