Brianchon (crater)
lunar crater

Brianchon is a lunar impact crater that is located along the northwestern limb of the Moon. Due to its location, from the Earth the crater is seen from the edge and its visibility is somewhat affected by libration. Thus for a more detailed view, the crater must be viewed from orbit.
This crater lies just to the west of the crater Pascal, and Desargues is to the southeast. To the south of Brianchon along the limb is the crater Cremona, while Lindblad lies to the southwest just on the far side of the Moon.
This formation dates to the Pre-Nectarian period of the lunar geologic timescale. Brianchon has been worn and eroded by a history of impacts that followed its creation. The most prominent of these are a pair of craters that lie across the northern rim, and Brianchon B which intrudes slightly into the southern rim. Brianchon A forms an outward bulge in the rim to the northwest, but otherwise merges seamlessly into the crater formation. There is also a concentric crater formation intruding into the exterion of the southeastern rim.
This brief starts where responsible research should: with the source description of “Brianchon (crater)” as lunar crater. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as lunar crater. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q2741596. Authority coordinates are 74.750, -88.360. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
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.
