Wunda (crater)

From Wikipedia, the free encyclopedia

Wunda is a large ring of bright material on the surface of Uranus' moon Umbriel. It is a crater of some kind, but the reason for its brightness, which stands out from the very dark composition of the moon as a whole, is unknown. The feature is more than 140 km in diameter and it is located near the equator of Umbriel .

It is named after Wunda, a dark spirit of Indigenous Australian aboriginal mythology.
