Drude (crater)
Encyclopedia
Drude is a lunar
impact crater
that lies on the far side of the Moon
, in the rugged Montes Cordillera
range that forms the outer ring around the Mare Orientale
impact basin. It is located just behind the west-southwest limb, and this area is sometimes brought into sight from Earth
during favorable libration
s. However, even at such times, the crater is viewed from the edge and little detail can be seen.
This is a circular crater with a relatively sharp edge, sloping inner walls and a fairly level interior. It has not been significantly eroded, and is generally unremarkable. The nearest craters of note are Graff
to the south-southeast and Focas
to the north-northwest. The surrounding area is of note for the tumultuous terrain created by the ejecta
from Mare Imbrium.
The satellite crater formerly known as Drude S was renamed Heyrovský

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...

Mare Orientale
Mare Orientale is one of the most striking large scale lunar features, resembling a target ring bull's-eye. Located on the extreme western edge of the lunar nearside, this impact basin is difficult to see from an Earthbound perspective.Material from this basin was not sampled by the Apollo program...

In astronomy, libration is an oscillating motion of orbiting bodies relative to each other, notably including the motion of the Moon relative to Earth, or of Trojan asteroids relative to planets.-Lunar libration:...

Graff (lunar crater)
Graff is a small lunar crater that lies along the southwestern limb of the Moon. It is located to the west of the Vallis Bouvard depression in the southern part of the ejecta blanket that surrounds the Mare Orientale impact basin...

Focas (lunar crater)
Focas is a small lunar impact crater that lies on the far side of the Moon, just past the southwestern limb. In this location the crater is occasionally brought into view due to libration, but not much detail can be seen because the crater is viewed from the side.The crater is situated in the wide...

Heyrovsky (crater)
Heyrovsky is a small lunar impact crater on the far side of the Moon. This crater lies just beyond the southwestern limb, in an area of the surface that is sometimes brought into view of the Earth during periods of favorable libration and illumination by sunlight...
