Bridgman (crater)
Encyclopedia
Bridgman is a lunar
impact crater
that is located on the far side of the Moon
. It lies in the northern hemisphere
, to the northwest of the crater Kurchatov
. To the west-southwest is the old formation Becquerel
, and eastward are the craters Pawsey
and Wiener
.
The prominent outer wall of Bridgman is only somewhat worn, and retains much of its original detail including traces of terrace structures and slumping. The rim is not quite circular, having a slight polygon
al appearance with rounded corners. There is a notable inward bulge of the wall at the south end. The interior floor is generally level, with a central peak formation at 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...

Sphere
A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point...

Kurchatov (crater)
Kurchatov is a lunar impact crater that is located on the Moon's far side. It is just to the southwest of the crater Wiener, and farther to the southeast of Bridgman...

Becquerel (lunar crater)
Becquerel is a lunar crater that lies in the northern hemisphere on the far side of the Moon. This is an ancient and heavily worn formation that is now little more than an irregular depression in the surface...

Pawsey (crater)
Pawsey is a worn impact crater that lies next to the northern outer ramparts of the crater Wiener, on the far side of the Moon. To the east-northeast of Pawsey is the large crater Campbell, and farther to the west is Bridgman....

Wiener (crater)
Wiener is a lunar impact crater that lies on the Moon's far side. It is located just to the southwest of the larger crater Campbell. To the southwest of Wiener is the heavily worn Kurchatov. To the east along the rim of Campbell is Von Neumann...

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...

Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Bridgman.| Bridgman | Latitude | Longitude | Diameter |
