Eponym	Jean V. Poncelet

Poncelet is the remains of a lunar crater that is located near the northern limb of the Moon. It lies to the east-northeast ot Pascal crater and northwest of Anaximenes crater. Like the later formation, Poncelet is a worn, eroded formation with an interior that has been flooded, either with lava or possibly ejecta. The outer rim is a low, circular ridge with a narrow break to the south and a wider breach to the northeast. The interior floor is pock-marked with many tiny craterlets, the most notable of which is 'Poncelet H', located just to the southeast of the mid-point.

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 Poncelet crater.
