Heaviside (lunar crater)
Encyclopedia
Heaviside is a large lunar
impact crater
that is located on the far side of the Moon
. It is attached to the eastern rim of the equally large walled plain Keeler
, although Keeler is somewhat less eroded. To the northwest lies the crater Stratton
, and to the southeast is the prominent Aitken
.
The outer wall of Heaviside has been worn and eroded by subsequent impacts, particularly to the north and south. Only the eastern rim remains relatively intact, while the western rim has been slightly distorted by the adjacent Keeler impact.
The relatively flat interior floor is marked by many small craterlets and rugged terrain to the southeast and west. The most notable of these are the satellite craters Heaviside N in the south, Heaviside Z in the north, and the bowl-shaped Heaviside E near the eastern rim.
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...

Impact crater
In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Keeler (lunar crater)
Keeler is a large lunar crater that lies on the Moon's far side. It is connected along the eastern edge to Heaviside, a walled plain of similar dimensions. Keeler, however, is the younger of the two formations, with more clearly delineated features...

Stratton (crater)
Stratton is a lunar impact crater on the Moon's far side. It is located to the north of the large craters Keeler and Heaviside, and less than one crater diameter to the south of Dewar....

Aitken (crater)
Aitken is a large lunar impact crater that lies on the far side of the Moon, named for Robert Grant Aitken, an American astronomer specializing in binary stellar systems. It is located to the southeast of the crater Heaviside, and north of the unusual formation Van de Graaff. Attached to the...
