Ehrlich is a small
lunarimpact crater named after the German scientist
Paul Ehrlich. It is located in the northern
hemisphere on the
Moon's
far side. It lies within a rugged region that has been extensively bombarded by impacts of comparable size. Ehrlich lies about midway between the craters
Parsons to the south and the heavily worn
Guillaume 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.
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 Ehrlich.
