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...

. It is located to the northeast of Henderson

Henderson (crater)

Henderson is a crater on the far side of the Moon. It is located to the east of the huge walled plain Mendeleev. This is a worn crater with a shallow rim. No significant craters overlie the rim or interior, but a smaller, worn crater is attached to the southern outer rim. A ridge of material runs...

Kohlschütter (crater)

Kohlschütter is a lunar crater that cannot be viewed directly from the Earth as it lies on the Moon's far side. It is located a couple of hundred kilometers to the southeast of the Mare Moscoviense, and due south of the smaller crater Nagaoka...

.

This is an undistinguished impact crater that is roughly circular in form, with a slight outward bulge to the northwest. This bulge may be due to the merger of a smaller impact with the rim. The rim edge is somewhat worn, with indistinct features and a few tiny craterlets along the edge. The interior floor has a ridge of material protruding inwards from the southern inner wall, but is otherwise marked only by a number of tiny 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 Mills.
