Hédervári (crater)
Encyclopedia
Hédervári is a lunar
crater
that is located in the southern part of the Moon
, only a few crater diameters from the south lunar pole. It is attached to the northern rim of the larger crater Amundsen
, and lies south of Hale
. Due to its location, this crater is viewed nearly from the edge from Earth
, which hinders the amount of detail that can be observed. It is also illuminated obliquely by the Sun, and the interior is often cloaked in shadows.
This is an eroded crater with a rough and irregular outer rim. The smaller crater Amundsen C lies across the northern rim, as well as the inner wall and part of the interior floor. The outer rampart of Amundsen covers the southern part of the inner wall. The interior floor is rough in places, particularly in the western half. The eastern floor is more level and featureless. There is a mount of rough ground about the mid-point.
This feature was previously identified as Amundsen A before being assigned a name by the IAU
after Péter Hédervári, Hungarian astronomer.

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...

Amundsen (crater)
Amundsen is a large lunar impact crater located near the south pole of the Moon, named after the Norwegian explorer Roald Amundsen. It lies along the southern lunar limb, and so is viewed from the side by an observer on the Earth. To the northwest is the crater Scott, a formation of similar...

Hale (lunar crater)
Hale is a relatively young lunar impact crater that is located on the southern limb of the Moon. Over half the crater lies on the far side of the Moon, and from the Earth this formation is viewed from the side. Thus the crater must be viewed from orbit in order to discern much detail. The nearest...
