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...

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...

. It is attached at the southern end to the northern rim of the crater Dirichlet

Dirichlet (crater)

Dirichlet is a lunar impact crater that is located on the Moon's far side. It is attached to the southern outer rim of the crater Henry. To the south-southeast is the much larger crater Tsander....

. Less than a crater diameter to the northeast is the large crater Mach

Mach (crater)

Mach is a large lunar crater of the class known as a walled plain. It is located on the far side of the Moon and cannot be viewed directly from the Earth. Nearby craters of note include Joule to the northeast, Mitra attached to the western outer rim, and Henyey to the southwest.This is a prominent...

, and to the northwest lies Mitra

Mitra (crater)

Mitra is a lunar crater that is attached to the western outer rim of the larger crater Mach, on the far side of the Moon. Just to the west of Mitra is Bredikhin, and to the south-southeast lies Henyey. It is named after Sisir Kumar Mitra....

.

This is a worn and eroded crater that has been partly disintegrated by subsequent impacts. The elongated crater Henyey U is attached to the western outer rim. The western interior floor of Henyey is disrupted by some small craters.

Satellite craters

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 Henyey.
