Mairan (Crater)Mairan is a lunar impact crater that is located on a highland peninsula between Oceanus Procellarum to the west and Mare Imbrium to the east. To the north-northeast is the comparably-sized Sharp crater. Northwest of Mairan is the heavily eroded Louville crater. The outer rim of Mairan has not been significantly eroded or impacted, and retains a sharp edge. The surface about Mairan is rough and irregular, with a multitude of many tiny craters, particularly to the south and west. The inner walls display some terracing, and flow down to a relatively flat interior floor. In the mare due west of Mairan crater is a small lunar dome designated 'Mairan T'. The dome has a tiny crater at the summit. There is also a sinuous rille along the southwest edge of the highland peninsula containing Mairan crater. It is designated Rima Mairan, and follows a north-south course for a length of about 100 kilometers. 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 Mairan crater. | idth="25%" style="background:#eeeeee;" |Latitude | width="25%" style="background:#eeeeee;" |Longitude | width="25%" style="background:#eeeeee;" |Diameter | | lign="center"|A | align="center"|38.6° N | align="center"|38.8° W | align="center"|16 km | | lign="center"|C | align="center"|38.6° N | align="center"|46.0° W | align="center"|7 km | | lign="center"|D | align="center"|40.9° N | align="center"|45.4° W | align="center"|10 km | | lign="center"|E | align="center"|37.8° N | align="center"|37.2° W | align="center"|6 km | | lign="center"|F | align="center"|40.3° N | align="center"|45.1° W | align="center"|9 km | | lign="center"|G | align="center"|40.9° N | align="center"|50.8° W | align="center"|6 km | | lign="center"|H | align="center"|39.3° N | align="center"|40.0° W | align="center"|5 km | | lign="center"|K | align="center"|40.8° N | align="center"|41.0° W | align="center"|6 km | | lign="center"|L | align="center"|39.0° N | align="center"|43.2° W | align="center"|6 km | | lign="center"|N | align="center"|39.2° N | align="center"|45.5° W | align="center"|6 km | | lign="center"|T | align="center"|41.7° N | align="center"|48.3° W | align="center"|3 km | | lign="center"|Y | align="center"|42.7° N | align="center"|44.0° W | align="center"|7 km |
