Impact crater

In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Macrobius (crater)

Macrobius is a prominent lunar impact crater located to the northwest of the Mare Crisium. It lies on the southeast edge of the Lacus Bonitatis, a small lunar mare. The somewhat smaller crater Tisserand lies just to the east....

Sinus Amoris

Sinus Amoris extends northward from the northeast end of the Mare Tranquillitatis. It is located at selenographic coordinates 18.1° N, 39.1° E, and lies within a diameter of 130 km. To the north of the bay are the jumbled Montes Taurus peaks.Near the southern end of the bay where it outlets...

. It lies just to the north-northeast of Carmichael

Carmichael (crater)

Carmichael is a lunar impact crater that is located along the eastern edge of the Sinus Amoris, in the northeastern quadrant of the Moon's near side. It lies within a couple of crater diameters south-southwest of the smaller crater Hill. Further to the east-northeast is the prominent crater Macrobius...

, another renamed satellite crater of Macrobius.

This is a circular, bowl-shaped crater with an inner wall that has a relatively high albedo

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...

 compared to the surrounding terrain. The inner walls are symmetrical in form, and slope gently down to the small floor at the mid-point, a surface about one-fourth the diameter of the crater. This formation is not significantly eroded, and is otherwise indistinguishable from many similar craters on the Moon
