Caventou (Moon)

Named after Joseph-Bienaimé Caventou - French chemist, pharmacologist (1795-1877).

Caventou is a tiny lunar impact crater located in the western part of the Mare Imbrium. Prior to being renamed by the IAU in 1976, it had the designation La Hire D, being associated with the mountain Mons La Hire to the southeast. However, the name Caventou appeared on some maps as early as 1974. (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.
