Schmidt is a small lunar impact crater that is located near the southwest edge of Mare Tranquillitatis, to the southwest of the Ritter–Sabine crater pair, the first being about 12 km apart. This formation is circular and bowl-shaped, with little appearance of wear due to subsequent impacts. The interior has a higher albedo than the surrounding terrain, giving it a light appearance. The exterior consists of hummocky terrain with many boulders, ranging up to 100 m or more in diameter.
