Rumford (crater)
Encyclopedia
Rumford is a lunar
impact crater
that lies on the far side of the Moon
. It is located to the northwest of the large crater Oppenheimer
, and to the east-southeast of Orlov
.
This crater lies across the eastern rim of the larger satellite crater Rumford T. The perimeter is somewhat rounded and polygon
al in shape, with an outward protrusion along the eastern edge. The inner walls have slumped along the eastern half to produce a shelf along the sides. The interior floor has a lower albedo
than the surrounding terrain
, and there is a small central ridge 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...

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...

Oppenheimer (crater)
Oppenheimer is a large lunar crater that lies on the Far side of the Moon. It lies along the western outer ampart of the immense walled plain Apollo. Nearby features of note include the dark-floored crater Maksutov to the southwest, and Davisson to the west-southwest...

Orlov (crater)
Orlov is a lunar impact crater. It is located on the Moon's far side, to the northeast of the larger crater Leeuwenhoek. To the north-northwest of Orlov is De Vries, and to the east-southeast is Rumford....

Polygon
In geometry a polygon is a flat shape consisting of straight lines that are joined to form a closed chain orcircuit.A polygon is traditionally a plane figure that is bounded by a closed path, composed of a finite sequence of straight line segments...
