Segner (crater)
Encyclopedia
Segner is a lunar
crater
located near the southwestern limb of the Moon
, to the northeast of the giant walled plain Bailly
. The crater Zucchius
is a few kilometers to the south-southwest of the rim, and to the north east lies the unusual formation Schiller
. The smaller crater Weigel
is located to the east.
Segner has a low, worn rim, and is generally much less prominent than the nearby Zucchius. The floor is distinguished only by a pair of small craterlets and a slightly undulating surface. There is no indication of a central peak. A low ridge runs to the north from the edge of the northern 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...

Bailly (crater)
Bailly is a lunar impact crater that is located near the south-west limb of the Moon. The oblique viewing angle gives the crater a foreshortened appearance, and the location near the limb can limit visibility due to libration...
. The crater Zucchius
Zucchius (crater)
Zucchius is a prominent lunar impact crater located near the southwestern limb. Because of its location the crater appears oblong-shaped due to foreshortening. It lies just to the south-southwest of the crater Segner, and northeast of the much larger walled plain Bailly...

Schiller is an oddly shaped lunar impact crater located in the southwestern sector of the Moon. To the east is the crater Bayer and to the southeast is Rost....

Weigel (crater)
Weigel is a small lunar crater that is located in the southwestern part of the Moon. It lies to the west-southwest of the slightly larger crater Rost, and due south of the elongated Schiller...
