Ansgarius (crater)
Encyclopedia
Ansgarius is a lunar
impact crater
that is located near the eastern limb of the Moon
. When viewed from the Earth
, the crater has a highly oval shape due to foreshortening, but the rim is actually nearly circular. To the northwest of Ansgarius is the crater La Pérouse
, and south is Behaim
.
The rim of Ansgarius is not significantly worn, and has a terraced interior surface. The southwest rim appears somewhat flattened rather than round, and intrudes into an older formation of which little remains except the western rim. There is an outward notch in the north-northeastern wall. The interior floor of Ansgarius is relatively flat, with only tiny craterlets to mark the surface.
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...

La Pérouse (crater)
La Pérouse is a lunar impact crater that is located near the eastern limb of the Moon. It lies northwest of the larger crater Ansgarius, and to the east of Kapteyn. This crater appears foreshortened due to its location, but the rim is nearly circular when viewed from orbit.The rim of La Pérouse is...

Behaim (crater)
Behaim is a lunar impact crater that is located near the eastern limb of the Moon, just to the south of the crater Ansgarius. To the south of Behaim is the crater Hecataeus, and to the east-southeast is Gibbs....
