Atwood (Moon)

Named after George Atwood - British mathematician, physicist (1746-1807).

Atwood is a small lunar impact crater on the Mare Fecunditatis, to the northwest of the prominent crater Langrenus. It forms a triple-crater formation with Naonobu attached to the north rim and Bilharz near the west rim. All three were satellite craters of Langrenus before being renamed by the IAU.

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.
