Brianchon is a lunar 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 Pascal crater, and Desargues crater is located to the southeast. To the south of Brianchon along the limb is Cremona crater, while Lindblad crater lies to the southwest just on the far side of the Moon.
The Brianchion crater 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 'Brianchion 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. The remainder of the outer wall has been rounded, and is covered in a number of tiny craterlets.
The floor of the crater is relatively level, and is marked by a multitude of tiny craterlets. The most prominent of these is a small, bowl-shaped crater just to the northwest of the mid-point. The southern portion of the crater floor in particular contains a grouping of several tiny craterlets.

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 Brianchon crater.
