Diyar Planitia is a region of relatively un-cratered terrain on Saturn

Saturn

Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Saturn is named after the Roman god Saturn, equated to the Greek Cronus , the Babylonian Ninurta and the Hindu Shani. Saturn's astronomical symbol represents the Roman god's sickle.Saturn,...

Enceladus (moon)

Enceladus is the sixth-largest of the moons of Saturn. It was discovered in 1789 by William Herschel. Until the two Voyager spacecraft passed near it in the early 1980s very little was known about this small moon besides the identification of water ice on its surface...

. It is located at 0.5° North Latitude

Latitude

In geography, the latitude of a location on the Earth is the angular distance of that location south or north of the Equator. The latitude is an angle, and is usually measured in degrees . The equator has a latitude of 0°, the North pole has a latitude of 90° north , and the South pole has a...

Longitude

Longitude is a geographic coordinate that specifies the east-west position of a point on the Earth's surface. It is an angular measurement, usually expressed in degrees, minutes and seconds, and denoted by the Greek letter lambda ....

Voyager program

The Voyager program is a U.S program that launched two unmanned space missions, scientific probes Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable planetary alignment of the late 1970s...

probes could not resolve whether Diyar Planitia is part of the ridged plains unit of Enceladus (Kargel and Pozio 1996) or the smooth plains unit (Rothery 1999), which is thought to be the youngest terrain on the moon. The more recent (and higher resolution) Cassini images show that Diyar is a region of relatively 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.

Diyar Planitia is bounded on the north and east by a band of grooved terrain named Harran Sulci

, it is likely that the formation of Diyar Planitia and Harran Sulci are related.

Diyar Planitia is named after the country that Khudadad's father rules in Arabian Nights.
