Vuver (crater)
Vuver is a crater on the surface of Uranus' moon Umbriel. It is estimated to be 98 km in diameter. The longitude and latitude of its center are 311.6° and −4.7°, respectively.
Vuver has a bright central peak, which is one of the few bright albedo features on Umbriel that really stands out against Umbriel's low albedo.
The crater is named after Vuver, a Volga Finns evil spirit.
