Poncelet (crater)
Poncelet is the remains of a lunar impact crater that is located near the northern limb of the Moon. It lies to the east-northeast of the crater Pascal and northwest of Anaximenes. Like the latter 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 midpoint.
