Crüger A (Moon)

Satellite Feature of Crüger

Named after Peter Crüger - German mathematician (1580-1639).

Crüger is a lunar crater that is located to the northeast of the much larger walled plain Darwin. The most distinctive feature about this crater is very dark interior floor that is one of the lowest albedo features. The surface has been covered in basaltic lava and has only been exposed to a minimal amount of deposition from impact ejecta. The floor is nearly featureless, with only a tiny craterlet near the center and few other even more diminutive impacts. (wikipedia entry)
