Pontécoulant is a prominent lunar impact crater that is located in the southeastern part of the Moon. 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. The rim is somewhat worn but retains much detail. The crater partly overlies the older and smaller Pontécoulant E along the southern rim, and has several tiny craterlets on the eastern inner wall and one to the southwest.

The inner floor is nearly flat, with some rough ground near the southern rim and some low central peaks located southwest of the midpoint. There is a small but prominent crater located at the center of the floor, and several other tiny craterlets scattered across the inner surface.

The eponym of this crater is Philippe Gustave Doulcet, le Comte de Pontécoulant.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Pontécoulant.

gollark: The additional spending of the top ones apparently goes on research quite a lot. That doesn't impact teaching quality much in *most* areas, since I don't think that much of your education is going to be in state of the art research. Maybe the last year.

gollark: Prestigious is the more accurate word I guess.

gollark: I expect there are significant diminishing returns with actual teaching quality in the trendier universities.

gollark: Increasingly, if you want to learn a thing for learningous purposes, you can just get free/cheap material on it off the internet.

gollark: Although over here there are rather large variations in income 5 years after graduation by degree.
