Duban is a crater in the northern hemisphere of Saturn's moon Enceladus. Duban was first seen in Voyager 2 images, though the crater has also been seen in much higher resolution Cassini images. In the Cassini image, evidence for significant tectonic deformation can be seen along the northwest rim 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.
