Chladni (Moon)

Named after Ernst Florens Friedrich Chladni - German physicist (1756-1827).

Chladni is a small lunar impact crater that lies near the northwest edge of Sinus Medii, in the central part. The crater is named for German physicist and musician Ernst Chladni who, in 1794, wrote the first book on meteorites. The rim of the crater is roughly circular, and there is a small central floor at the midpoint of the sloping inner walls. This feature has a higher albedo than the surrounding terrain.

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.
