Briggs is a lunar crater that is located in the western part of the Oceanus Procellarum lunar mare, to the east of the large Struve walled-plain. It lies to the northeast of the Eddington walled-plain, and north-northwest of Seleucus crater. The isolated position of this crater on the mare, near the northwestern limb of the Moon, makes it relatively easy for an Earth-bound observer to locate.
The outer rim of Briggs is not quite circular, with outward bulges to the north-northeast and southward. At the mid-point of the crater floor is a central ridge, extending to the north.
[edit] 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 Briggs crater.
