Named after Maurice Darney - French astronomer (1882-1958).
Darney is a small lunar crater on the region where the Mare Nubium joins the Oceanus Procellarum. To the south is the lava-flooded crater Lubiniezky. The southern rim is attached to a series of low ridges that extend to the southwest. This is a bowl-shaped formation with a small interior floor at the midpoint of the sloping inner walls.

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.
