Foster is a small lunar crater that lies to the southeast of the larger Joule crater, on the far side of the Moon. The rim of Foster is slightly eroded, and the narrow inner walls slope directly down to the relatively dark interior floor. The rim has a small outward bulge along the southwest side. There is a small craterlet on the floor next to the northern rim. A tiny impact in the southeast part of the crater interior is surrounded by a small skirt of high albedo material, producing a bright patch.

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 Foster crater.
