Peri-Banu (crater)  Peri-Banu is a crater in the northern hemisphere of Saturn's moon Enceladus. Peri-Banu was first discovered in "Voyager 2" images but was seen at much higher resolution, though near the terminator, by "Cassini". It is located at 62° North Latitude, 322.9° West Longitude and is 18 kilometers across. The western portion of the crater is largely absent, either buried or disrupted by the eastern margin of Samarkand Sulci. A large, dome-like structure occupies the interior of the crater, caused by infill of material from Samarkand Sulci or from viscous relaxation. The name comes from Pari-Banou, a genie-woman from "Arabian Nights", incarnation of beauty, who marries Ahmed and helps him fulfill the demands of his father.
