Haidinger (crater)
Encyclopedia
Haidinger is a lunar
impact crater
that is located in the southwestern part of the Moon
. Just to the southwest of the crater is the small lunar mare
named Lacus Timoris
. Haidinger lies northwest of the crater Wilhelm
and east of the irregular formation Hainzel
.
The outer rim of this crater is nearly circular, with slight outward bulges along the western and northeastern parts of the rim. The satellite crater Haidinger B is attached to the exterior of the eastern rim, and Haidinger A lies close to the northeastern rim. There is a small crater-like divot along the southern inner wall. The interior floor has a low ridge in the northern 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...

Lunar mare
The lunar maria are large, dark, basaltic plains on Earth's Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for "seas", by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich compositions, and...
named Lacus Timoris
Lacus Timoris
Lacus Timoris is a small lunar mare on the Moon. It is located at 38.8° S, 27.3° W and is 117 km in diameter. It was discovered in 1976 and its name was approved by the International Astronomical Union at a meeting in Grenoble....

Wilhelm (crater)
Wilhelm is a lunar crater in the southern part of the Moon, to the west of the prominent Tycho. Portions of the ray material from Tycho lie across the rim and floor of Wilhelm. Attached to its southern rim is the crater Montanari, while Lagalla is attached to the southwest. To the north-northeast...
