Al-Mustazi (Enceladus)

Father of benevolent prince Al-Mustansir in "The Hunchback’s Tale"

Al-Mustazi is an impact crater located on the anti-Saturn hemisphere of Saturn's moon Enceladus. Cassini observed numerous southwest-northeast trending fractures cutting across the southwest rim , forming canyons several hundred meters deep. These fractures were deflected by the weakened regolith produced by the Al-Mustazi impact. (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.
