Comrie (crater)
Encyclopedia
Comrie is a lunar
crater
. It is located on the rugged far side of the Moon
relative to the Earth
, beyond the western limb. Nearby craters of note include Ohm
to the south-southwest, Shternberg
to the southwest, and Parenago
to the northeast.
This feature forms the central member of a formation of three connected craters. A slightly smaller crater is attached to the northern end, and the two share a straight rim. This crater also lies across the northern part of a larger, heavily worn feature to the south, and little of Comrie's rim survives along its southern extent. The remaining rim is worn and eroded.
Within the crater interior, a small crater lies near the northwest rim, a smaller crater just to the southwest of the mid-point, and a still smaller crater along the surviving southwest rim. There is a low central ridge at the mid-point. The eastern half of the interior floor is somewhat irregular, but contains only a few tiny craterlets. Streaks from the ray system
of Ohm lie across the interior of Comrie, particularly in the western half.
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...

Ohm (crater)
Ohm is a lunar impact crater that is located on the far side of the Moon. It lies to the south of the crater Comrie, and the satellite crater Comrie K is attached to Ohm's northeastern rim...
to the south-southwest, Shternberg
Shternberg (crater)
Shternberg is an eroded lunar impact crater on the Moon's far side. It lies just to the west-northwest of the crater Ohm, and is completely covered by higher-albedo material from the ray system that surrounds Ohm. To the west-southwest of Shternberg is Weyl, and to the west-northwest is Comstock...

Parenago (crater)
Parenago is an impact crater on the Moon'sfar side, behind the eastern limb. Nearly attached to the east-southeastern outer rim of Parengo is the crater Berkner. To the south-southwest lies Comrie....

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...
