Sharrkan (Enceladus)

Son of the great King Omar in "The Tale of King Omar and his Sons"

Sharrkan is an impact crater in the northern hemisphere of Saturn's moon Enceladus. At only 3.6 kilometers across, Sharrkan is the smallest named crater on Enceladus, though numerous, smaller, unnamed craters have been observed. The crater has a basic bowl-shape typical of small, simple craters. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On Enceladus they are named after people and places from Burton's Arabian Nights.
