Dove is a small lunar crater that is located in the rugged lunar highlands in the southeastern part. It lies to the north of the prominent crater Pitiscus. This is a heavily worn and eroded crater with a rim that is overlaid by multiple small craters. In particular the satellite crater Dove C has broken into the southwestern rim and a gap joins the floor of the two formations. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
