Harvey (crater)
Encyclopedia
Harvey is a lunar
impact crater
that is located on the far side of the Moon
from the Earth
. It lies astride the eastern rim of the much larger crater Mach
, and the outer rampart of Harvey extends part way across the interior floor. Some distance to the north of Harvey is the crater Joule
, and equally far to the east-southeast is Kekulé
.
The rim of Harvey is mildly eroded, and a small craterlet lies in the western part of the interior floor. There is a low central peak at the mid-point. Ray material
from Joule T to the north crosses the floor of Harvey, passing along the western side of the mid-point and nearly bisecting the interior.
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...

Mach (crater)
Mach is a large lunar crater of the class known as a walled plain. It is located on the far side of the Moon and cannot be viewed directly from the Earth. Nearby craters of note include Joule to the northeast, Mitra attached to the western outer rim, and Henyey to the southwest.This is a prominent...

Joule (crater)
Joule is a lunar impact crater that lies on the far side of the Moon. It is located to the north-northeast of the walled plain Mach. To the northwest of Joule is the crater Blazhko....

Kekulé (crater)
Kekulé is a lunar crater on the far side of the Moon. It lies just to the west-southwest of the larger crater Poynting, on the edge of the ejecta skirt surrounding the walled plain Hertzsprung to the southeast....

Ray system
A ray system comprises radial streaks of fine ejecta thrown out during the formation of an impact crater, looking a bit like many thin spokes coming from the hub of a wheel. The rays can extend for lengths up to several times the diameter of their originating crater, and are often accompanied by...
