Le Gentil (Moon)

Named after Guillaume Hyazinthe Gentil - French astronomer (1725-1792).

Le Gentil is a lunar crater that is located in the south-southwest part , near the limb, and is nearly attached to the southern rim of the huge walled plain Bailly. To the southeast is the large crater Drygalski. Due to its location, this crater appears considerably foreshortened and is viewed from an oblique angle by observers on the Earth. As a formation this crater has been deeply eroded by impacts, leaving a heavily worn formation that is little more than a depression in the surface. (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.
