Dione


Like their semi-divine namesakes, Dione's twin craters Romulus and Remus (just above-right of center) stand together. Dido, the larger crater featuring a central peak, lies just to the southeast on the day/night terminator.

Lit terrain seen here is on the Saturn-facing hemisphere of Dione. North on Dione is up. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 28, 2013.

The view was obtained at a distance of approximately 870,000 miles (1.4 million kilometers) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 77 degrees. Image scale is 5 miles (8 kilometers) per pixel in the original image. This image has been zoomed in by a factor of 1.5 to enhance clarity.
