Wunda is a large crater on the surface of Uranus' moon Umbriel. It is 131 km in diameter and is located near the equator of Umbriel. The crater is named after ''Wunda'', a dark spirit of Australian aboriginal mythology. 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. The reason for its brightness, which stands out from the very dark composition of the moon as a whole, is unknown. == References == Citations Sources * * * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wunda (crater)」の詳細全文を読む スポンサード リンク
