Named after Michael Collins - American astronaut (1930-Live).
Collins is a tiny lunar impact crater located on the southern part of the Mare Tranquillitatis. It is located about 25 kilometers to the north of the Apollo 11 landing site. About 15 kilometers to the west-northwest is the landing site of the Surveyor 5 lunar probe. This crater was previously identified as Sabine D before being renamed by the IAU. (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.
