Cleopatra (Venus)

Named after Cleopatra - Egyptian queen, notable for love affairs with Julius Caesar and Mark Anthony (69-30 B.C.).

Cleopatra is an impact crater on Venus, in Maxwell Montes. Cleopatra is a double-ring impact basin about 100 kilometers deep. A steep-walled, winding channel a few kilometers wide breaks through the rough terrain surrounding the crater rim. A large amount of lava originating in Cleopatra flowed through this channel and filled valleys in Fortuna Tessera. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On Venus they are named after deceased women who have made outstanding or fundamental contributions to their field (if over 20 km). If smaller common female first names are used.
