 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 crater sharp. northwest of mairan is the heavily eroded louville. the outer rim of mairan has not been significantly eroded or impacted, and retains a sharp edge. the surface around 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 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. it is designated rima mairan, and follows a northâsouth 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 midpoint that is closest to mairan. {| class="wikitable" !width="25%" style="background:#eeeeee;" |mairan !width="25%" style="background:#eeeeee;" |latitude !width="25%" style="background:#eeeeee;" |longitude !width="25%" style="background:#eeeeee;" |diameter |- |align="center"|a |align="center"|38.6Â° n |align="center"|38.8Â° w |align="center"|16&nbsp;km |- |align="center"|c |align="center"|38.6Â° n |align="center"|46.0Â° w |align="center"|7&nbsp;km |- |align="center"|d |align="center"|40.9Â° n |align="center"|45.4Â° w |align="center"|10&nbsp;km |- |align="center"|e |align="center"|37.8Â° n |align="center"|37.2Â° w |align="center"|6&nbsp;km |- |align="center"|f |align="center"|40.3Â° n |align="center"|45.1Â° w |align="center"|9&nbsp;km |- |align="center"|g |align="center"|40.9Â° n |align="center"|50.8Â° w |align="center"|6&nbsp;km |- |align="center"|h |align="center"|39.3Â° n |align="center"|40.0Â° w |align="center"|5&nbsp;km |- |align="center"|k |align="center"|40.8Â° n |align="center"|41.0Â° w |align="center"|6&nbsp;km |- |align="center"|l |align="center"|39.0Â° n |align="center"|43.2Â° w |align="center"|6&nbsp;
