EponymSpirit, Australian Aboriginal mythology

Yangoor is the largest known impact crater on the surface of the Uranian moon Ariel. A central-peak impact crater, it is about 78 km in diameter and is located approximately 450 km from Ariel's south pole. The northwestern edge of the crater was erased by formation of ridged terrain.[3] The crater lacks bright ejecta deposits and was imaged for the first time by the Voyager 2 spacecraft in January 1986.[4] The crater is named after a spirit that brings day in Australian Aboriginal mythology. The name Yangoor was officially approved by the International Astronomical Union in 1988.[1]
