Valhalla Crater on Callisto. Callisto is the most heavily cratered satellite in the Solar System. Its surface has apparently been primarily sculpted by impacts. Valhalla is its largest crater - it's 360 km (225 miles) across and the rings extend to 1900 km (1190 miles) from its center. (Photo: NASA) ©Mona Evans,"Jupiter's Galilean Moons"

Crescent Dione from Cassini, October 11, 2005 ~ Thin crescent of cratered terrain is illuminated on Saturn's fourth largest moon, Dione.
