Poinsot K (Moon)

Satellite Feature of Poinsot

Named after Louis Poinsot - French mathematician (1777-1859).

Poinsot lies to the south of the walled plain Rozhdestvenskiy. 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. A number of tiny craterlets lie along the rim edge and inner walls, as well as across the level interior surface. (wikipedia entry)
