Named after Jean Louis Pons - French astronomer (1761-1831).
Pons is an lunar crater that is located to the west of the prominent Rupes Altai scarp. It lies to the southeast of the crater Sacrobosco, and southwest of Polybius. To the northwest along the same flank of the formation is the crater Fermat. The rim is somewhat elongated in shape, being longer along a northeast-southwest axis than in the perpendicular direction.

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.
