Eddington is the lava-flooded remnant of a lunar impact crater, located on the western part of Oceanus Procellarum. The western rim is attached to the wall of the walled plain Struve. To the east-southeast is the smaller but prominent crater Seleucus. South of Eddington is Krafft.
The south and southeastern rim of Eddington is almost completely gone, leaving only a few ridges and promontories in the lunar mare to trace the outline of the original crater. As a consequence, Eddington is now essentially a bay in the Oceanus Procellarum. 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
[edit]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.
