(22260) Ur is an asteroid of the central main belt that was discovered on October 19, 1979 by the Czech astronomer Antonín Mrkos at the Kleť Observatory ( IAU code 046) near Český Krumlov .
The asteroid is named after the Mesopotamian city of Ur . The name was given at the suggestion of the Czech astronomer Jana Tichá by the International Astronomical Union (IAU) on May 9, 2001. The letter coding of the provisional name of the asteroid, 1979 UR, which stands for the date of discovery, is identical to the name in this case. In Ur is the ziggurat of the moon god Nanna . For this reason, a sulcus (furrow or groove) on Jupiter's moon Ganymede was named after Ur as early as 1985 : Ur Sulcus .
