Ehrlich is a small lunar crater that is located in the northern hemisphere on the Moon's far side, relative to the Earth. It lies within a rugged region that has been extensively bombarded by impacts of comparable size. Ehrlich crater lies about midway between the Parsons crater to the south and the heavily-worn Guillaume crater to the north.
This is a worn crater with features that have become softened and rounded due to bombardment. A pair of small craters are attached to the exterior along the southern rim. The interior floor and inner walls are nearly featureless and there are no impacts of note within the rim.
[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 Ehrlich crater.
