Wunda (Crater)

Short description: Crater on Umbriel

Wunda is a bright feature at the top of this image of Umbriel.

[ ⚑ ] 7°54′S 273°36′E / 7.9°S 273.6°E / -7.9; 273.6^[1]

Wunda is a large crater on the surface of Uranus' moon Umbriel.^[2] It is 131 km in diameter and is located near the equator of Umbriel. The crater is named after Wunda, a dark spirit of Australia n aboriginal mythology.^[1]

Wunda has a prominent albedo feature on its floor, which takes the shape of a ring of bright material at least 10 km in radial width.^[3] The reason for its brightness, which stands out from the very dark composition of the moon as a whole, is unknown.^[2] It may be either a fresh impact deposit or a deposit of carbon dioxide ice, which formed when the radiolytically formed carbon dioxide migrated from all over the surface of Umbriel and got trapped inside relatively cold Wunda.^[4]
