Carmichael (crater)
Encyclopedia
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
. Carmichael was designated Macrobius A before being given its current name by the IAU
.
Carmichael is generally circular, with a small floor at the middle of the sloping interior walls. There is a low rise of scree
along the southeast inner wall. The crater is free of notable impacts along the rim or the interior, although a tiny craterlet is situated in the lunar mare
just outside the rim to the south-southwest.
Moon
The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

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...

Hill (crater)
Hill is a small lunar impact crater that is located to the west of the prominent crater Macrobius, near the eastern edge of the Sinus Amoris. This crater was previously designated Macrobius B before being given a name by the IAU...

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....

Scree
Scree, also called talus, is a term given to an accumulation of broken rock fragments at the base of crags, mountain cliffs, or valley shoulders. Landforms associated with these materials are sometimes called scree slopes or talus piles...

Lunar mare
The lunar maria are large, dark, basaltic plains on Earth's Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for "seas", by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich compositions, and...
