Tags: Crater.
Poinsot is a worn lunar crater that is located at the northern part of the Moon on the far side. It lies to the south of the walled plain Rozhdestvenskiy. To the south is the smaller crater Heymans.This formation has been heavily worn by subsequent impacts leaving a round-shouldered outer rim that is nearly even with the surrounding terrain and an inner surface that slopes down to the floor without terraces or horizontal features.
