to trace the outline of the original crater. As a consequence, Eddington is now essentially a bay in the

. The remainder of the rim is worn and irregular, forming a mountainous arc that is widest in the north. The floor is almost free of craters of significance, with the nearly submerged crater Eddington P lying in the southeast sector. If the crater once had a central peak, it is no longer evident. The crater was named after the British astronomer and mathematician Sir Arthur Eddington.

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 Eddington.
