Eponym | John Playfair |
Playfair is a lunar crater that is located in the rugged southern highlands on the near side of the Moon. It lies along the eastern rim of the eroded satellite crater 'Playfair G', a formation that is almost twice the diameter of Playfair itself. Playfair crater is nearly due north of Apianus crater, and to the southwest of the Abenezra-Azophi crater pair.
This crater is oval in shape, being slightly wider along the east-west axis. The rim is somewhat eroded, and tiny craterlets lie along the south and west rims. The interior floor is level and nearly featureless, with the only feature of the minor interest being a pair of tiny craterlets lying just to the east of the mid-point.
[edit] 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 Playfair crater.
