Bolyai (crater)
Bolyai is an old lunar crater that is located in the southern hemisphere on the far side of the Moon. To the southeast of Bolyai is the crater Eötvös, and to the north is Neujmin.
This crater has been heavily eroded and worn by subsequent impacts, leaving only a deformed remnant of the original rim that is overlaid by a multitude of lesser craters. The most notable of these is Bolyai D along the northeast rim and Bolyai W to the northwest. The latter is actually a formation of multiply overlapping craters.
The interior of the crater is relatively level, but rough in places due to impacts that have reshaped the surface. Near the mid-point, and from there towards the western rim, is a section of floor that has been resurfaced by lava flows. This area is smoother than the remainder of the floor, and has a lower albedo, giving it a dark appearance.
Satellite craters
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 Bolyai.
