Diyar Planitia is a region of un-cratered terrain on Saturn's moon Enceladus. The more recent Cassini images show that Diyar is a region of low, north-south trending ridges, with several younger fractures cutting across the region along the same trend. Very few impact craters have been found in Diyar, demonstrating the youthful age of the region. (wikipedia entry)
A planitia is a low plain. On Enceladus they are named after people and places from Burton's Arabian Nights.
