Slipher (lunar crater)
Encyclopedia
Slipher is a lunar
impact crater
that is located in the northern latitudes on the far side of the Moon
. The crater overlies the southwestern outer rim of the much larger walled plain D'Alembert
, and it occupies a portion of the interior floor of D'Alembert. To the south-southeast is the crater Langevin
.
Because it overlies D'Alembert, Slipher is a younger formation and it has undergone much less erosion. The rim is circular but has a somewhat irregular edge. The rim is jumbled and irregular where it intersects D'Alembert. Overlapping the western rim and inner walls of Slipher is the smaller Slipher S, a fresh feature with a sharp-edged outer rim. The interior floor of Slipher is somewhat uneven except in the northeast, and there is a cluster of low central ridges near the mid-point.
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...

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...
