Pannekoek (crater)
Encyclopedia
Pannekoek is a lunar
impact crater
that is situated on the far side of the Moon
, and cannot be seen directly from the Earth
. The crater lies along the northern edge of the slightly larger Dellinger
, and their common border forms an area of uneven terrain. Due north of Pannekoek is the huge walled plain Mendeleev
.
This is a worn and eroded crater, although the perimeter of the rim is still visible. The southern part of the interior floor is jumbled and irregular. There is a small crater next to the inner wall along the west-southwest part of the floor. A smaller crater also lies in the interior along the northeast inner wall. There are also several small craterlets on the floor.

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...

Mendeleev (crater)
Mendeleev is a large lunar impact crater that is located on the far side of the Moon, as seen from the Earth. The southern rim of this walled plain just crosses the lunar equator. Intruding into the eastern rim of Mendeleev is the crater Schuster...
