Ur sulcus
Ur Sulcus is the name of a broad furrow ( sulcus ) or groove on Jupiter's moon Ganymede . It is located in the area of approximately 35 ° to 60 ° north latitude and 170 ° to 185 ° west longitude on the side of Ganymede facing away from Jupiter , in the north-western area of the Marius Regio , which has many sulci.
Ur sulcus has a length of about 1000 kilometers. In the south it meets the Nippur Sulcus , in the north, connected by a narrow band of light surface material, is an extension of the Philae Sulcus . The partially eroded Kadi crater, for example, is located with a mean diameter of 87 kilometers on the Ur Sulcus at about 47 ° north latitude.
Sulci were formed on Ganymede by tectonic faults. They are located in areas with a relatively young and bright surface. Depressions in the northern Ur Sulcus have a northeast orientation. In younger sulci such as Elam Sulcus and Nippur Sulcus they have a northwest orientation.
designation
The sulcus was given a proper name in 1985 by the International Astronomical Union (IA). It is named after the Mesopotamian city of Ur , where the moon god Nanna was worshiped. An asteroid in the central main belt was also named after Ur in 2001: (22260) Ur .
