A thin crescent of cratered terrain is illuminated on Saturn's fourth largest moon, Dione.
Lit terrain seen here is on the Saturn-facing side of Dione (1123 kilometers, 698 miles across). North is up.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 17, 2010. The view was acquired at a distance of approximately 394,000 kilometers (245,000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 151 degrees. Image scale is 2 kilometers (1 mile) per pixel.
