Dione Lit by Sunshine and Saturnshine

Dione's lit hemisphere faces away from Cassini's camera, yet the moon's darkened surface features are dimly illuminated in this image, due to Saturnshine.

Dione and Saturn's Rings

Dione's beautiful wispy terrain is brightly lit alongside Saturn's elegant rings.

Comparing Enceladus and Dione

Although Dione (near) and Enceladus (far) are composed of nearly the same materials, Enceladus has a considerably higher reflectivity than Dione. As a result, it appears brighter against the dark night sky.

Chasms on Dione

While not bursting with activity like its system satellite Enceladus, the surface of Dione is definitely not boring.

NASA's Cassini imaging scientists processed this view of Saturn's moon Dione, taken during a close flyby on June 16, 2015.

Saturn's Dione From a Distance

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.

Dusk on Dione

In this recent view of Dione, the Cassini spacecraft looks on as the moon's slow rotation brings the terrain from day into night. Any residents of Dione would have plenty of time to read a few bedtime stories, though, since the moon's rotation period is 66 hours.
