Pons is an lunar crater that is located to the west of the prominent Rupes Altai scarp. It lies to the southeast of Sacrobosco crater, and southwest of the Polybius crater. To the northwest along the same flank of the formation is the Fermat crater.
The rim of Pons is somewhat elongated in shape, being longer along a northeast-southwest axis than in the perpendicular direction. The outer wall is irregular and notched, particularly at the northeastern end where it is partly overlain by the satellite crater 'Pons D' and multiple smaller formations. The interior is uneven, with low ridges projecting from the north and southeastern rims.
[edit] Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Pons crater.
