Al-Haddar (Enceladus)

The barber's second brother in "The Hunchback’s Tale"

Al-Haddar is an impact crater on Saturn's moon Enceladus, first discovered by the Voyager spacecraft. It is the northernmost and smallest crater of a prominent crater triplet on Enceladus' anti-Saturnian hemisphere Voyager 2 observations revealed a bowl-shaped, simple crater, compared to its larger, more complex southern neighbors, Shahrazad and Dunyazad craters.

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.
