Buffon is a 106 km impact crater that is located on the southern hemisphere on the lunar Far Side. It lies a crater diameter south of the large walled plain Chebyshev. To the northeast is the crater Langmuir (out of frame) and to the southwest is Leavitt.  Buffon lies nearly at the midpoint between these formations. The SE portion of the huge Apollo Basin remains visible in the NW portion of Ridge Section 155 just to the left of Lovell. Buffon is a worn and eroded crater formation, with a circular rim that can still be traced through the rugged terrain but which is irregular and rounded due to a history of lesser impacts. The most notable of these is a tiny crater which lays across the northern rim and the satellite crater Buffon D which lies along the inner eastern wall. The interior floor, although generally level, is equally rugged and irregular, particularly in the eastern half.
