on the Moon
's far side. Just to the southeast is the somewhat smaller cater Guillaume
, and to the west-southwest lies Dunér
. To the northwest of Perkin is the large walled plain D'Alembert
.
This is a worn and eroded crater formation with an outer rim that has been reshaped by several subsequent impacts. Laid along the inner wall to the east-northeast is a small crater. Small craterlets lie along the southern inner wall and the northwestern rim. Several smaller craterlets cut across the rim along the southwest and north.
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...

Guillaume (crater)
Guillaume is an old lunar crater on the Moon's northern hemisphere, and is located on the far side relative to the Earth. It lies just to the southeast of the slightly larger crater Perkin. This is a worn and eroded formation, with features that have been softened and rounded over time. A cluster...

D'Alembert (crater)
D'Alembert is a large lunar impact crater located in the northern hemisphere on the far side of the Moon, to the northeast of the somewhat smaller walled plain Campbell. Astride the southwest rim of D'Alembert is Slipher. To the north is the crater Yamamoto, and to the south-southwest lies Langevin...
