Poncelet (crater)
remains of a lunar 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.
This crater is named after French mathematician and engineer Jean V. Poncelet (1788–1867).

Why this record matters
“Poncelet (crater)” is worth following because a concise public description often conceals a longer documentary argument. Here, Poncelet, crater and remains provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 13, 2026. The linked authority identifier is Q2103504. Authority coordinates are 75.910, -54.570. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1788 and 1867.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
