Goeppert-Mayer is a crater on the planet Venus. It is 35 kilometers in diameter and lies above an escarpment at the edge of a ridge belt in Southern Ishtar Terra. (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.
