Pontécoulant (Moon)

Named after Philippe Gustave Doulcet, Comte De Pontécoulant - French mathematician (1795-1874).

Pontécoulant is a prominent lunar impact crater that is located in the southeastern part. Due to its position, the crater appears foreshortened from the Earth and it is difficult to observe much detail. Nearby craters include Hanno just to the northeast, and the comparably sized Helmholtz due south. This crater has terraced inner wall that is nearly circular, but with an outward extension to the southeast. (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.
