Al-Fakik (Enceladus)

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

Al-Fakik is an impact crater in the northern hemisphere of Saturn's moon Enceladus. The topography of the impact crater appears very subdued, suggesting that the crater has undergone significant viscous relaxation since its formation. In addition, fractures have disrupted the southeastern margin of the crater. (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.
