Golubkina is a crater on Venus. Golubkina is characterized by terraced inner walls and a central peak, typical of large impact craters on the Earth, Moon, and Mars. The terraced inner walls form at late stages in the formation of an impact crater, due to collapse of the initial cavity formed by the meteorite impact. The central peak forms due to rebound of the inner crater floor. (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.
