Named after Louis Feuillée - French natural scientist (1660-1732).
Feuillée is a small lunar impact crater in the eastern part of the Mare Imbrium. It lies less than a half crater diameter to the northwest of Beer, and the two formations form a nearly matched pair. To the west is the small but prominent crater Timocharis. Like Beer, Feuillée is a circular, 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.
