Schmidt (lunar crater)
Encyclopedia
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. 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.

Ritter (crater)
Ritter is a lunar crater located near the southwestern edge of Mare Tranquillitatis. It is the northwestern member of a crater pair with Sabine to the southeast. The two rims are separated by a narrow valley only a couple of kilometers wide. To the northwest is the crater Dionysius, and to the...

Sabine (crater)
Sabine is a lunar crater that forms a nearly matching pair with Ritter to the northwest. The two rims are separated by a distance of only a couple of kilometers. To the west is the bowl-shaped crater Schmidt, and farther to the north are Manners and Arago....

Albedo
Albedo , or reflection coefficient, is the diffuse reflectivity or reflecting power of a surface. It is defined as the ratio of reflected radiation from the surface to incident radiation upon it...
