Yangoor is the largest known crater on the surface of the Uranian moon Ariel. The name comes from a spirit that brings day in Australian Aboriginal mythology.[1] It is about 80 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.[2] The crater lacks bright ejecta deposits and was imaged for the first time by the Voyager 2 spacecraft in January 1986.[3]
