Mairan is an impact crater on the high plateau of the peninsula between Oceanus Procellarum in the west and Mare Imbrium in the east. In a north-northeast direction lies the Sharp crater, which is comparable in size, and the heavily eroded Louville crater to the northwest . Along the southwestern side of the peninsula runs a winding groove called Rima Mairan , which runs from north to south for a distance of about 100 kilometers .
The outer edge of Mairan was only insignificantly damaged by erosion and subsequent impacts and has retained its sharp-edged ridge. The environment is rough and irregular and, especially in the south and west, is pitted by a myriad of tiny craters. The inner walls of the crater have some terraces and slope down to a relatively flat crater floor.
In the Mare west of Mairan there is a small dome-shaped elevation called 'Mairan T'. This has a tiny crater at its highest point.
