Einstein is a large lunar crater that lies along the western limb of the Moon, making it difficult to observe from the Earth. The visibility of this formation is affected by libration effects, but even under the best conditions not much detail can be observed except from lunar orbit. Nearby craters of note include Moseley just to the north, Dalton along the eastern rim, Vasco da Gama just to the southeast, and Bohr crater to the south-southeast. The formation Vallis Bohr is visible to the south.

The outer rim of this walled plain has been all but obliterated by many small impacts. Only along the eastern wall, where it joins Dalton crater, does a significant rim still survive. Occupying the center of the interior floor is 'Einstein A', an impact crater with d inner walls and a central peak. The outer of this concentric crater spreads across the interior floor, covering over half the diameter of the Einstein crater. Several smaller craters also lie scattered across the floor, but there are sections of relatively flat surface in the southwest part of the floor.

Because it is only visible under very favorable conditions, this crater was only discovered as recently as 1952 by Patrick Moore. The original name for this formation was "Caramuel", but it was later changed to Einstein by the IAU.

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 Einstein crater.
