Naming Dunyazad; Sister of Scheherazade

Dunyazad is a large crater on Saturn's moon Enceladus first discovered by the Voyager spacecraft. It is named after Dunyazad, the sister of Scheherazade in The Book of One Thousand and One Nights.

Dunyazad is located at 41°54′N 200°36′W / 41.9°N 200.6°W / 41.9; -200.6[1] and is approximately 30.9 kilometers across, making it one of the largest craters on Enceladus. It is the southernmost crater of a prominent crater triplet on Enceladus' anti-Saturnian hemisphere (there is no evidence that the impacts are related or were formed from break-up of a single body, like Shoemaker-Levy 9). The craters to its north are Shahrazad, and Al-Haddar.[2] Voyager discovery images of this crater revealed an up-domed floor at Dunyazad, suggesting that the crater had been modified by viscous relaxation. Higher resolution views of Dunyazad taken by the Cassini Spacecraft during a close flyby on March 9, 2005 reveal not only an up-domed floor, but numerous tectonic fractures as well, particularly within the dome and northeastern crater rim.
