The lunar south pole is located on the center of the polar Antarctic Circle (80°S to 90°S). [2][4] (The axis spin is 88.5 degrees from the plane of the ecliptic.) The lunar south pole has shifted 5.5 degrees from its original position billions of years ago. [5] This shift has [6] changed the rotational axis of the Moon, allowing sunlight to ...
Shackleton is an impact crater that lies at the lunar south pole. The peaks along the crater's rim are exposed to almost continual sunlight, while the interior is perpetually in shadow . The low-temperature interior of this crater functions as a cold trap that may capture and freeze volatiles shed during comet impacts on the Moon.
Malapert Mountain is the bright peak near bottom center. Malapert is a lunar impact crater that lies near the south pole of the Moon, named for 17th century astronomer Charles Malapert. [2] From the Earth this formation is viewed from the side, limiting the amount of detail that can be seen. The crater is also illuminated at very low angles, so ...
Cabeus (crater) Cabeus Crater (left) as imaged by the Diviner instrument on the Lunar Reconnaissance Orbiter. Cabeus is a lunar impact crater that is located about 100 km (62 mi) from the south pole of the Moon. [3] At this location the crater is seen obliquely from Earth, and it is almost perpetually in deep shadow due to lack of sunlight.
Mons Mouton. Mons Mouton is the Moon 's tallest mountain that has been officially named. [1] The base to peak height of this flat-topped mountain is 6 km per altimetry data from the Lunar Reconnaissance Orbiter. [1][2] It lies between the craters Nobile and Malapert, within 6° of the lunar South Pole on the Moon's near-side.
A peak of eternal light (PEL) is a hypothetical point on the surface of an astronomical body that is always in sunlight. Such a peak must have high latitude, high elevation, and be on a body with very small axial tilt. The existence of such peaks was first postulated by Beer and Mädler in 1837. The pair said about the lunar polar mountains ...
The South Pole-Aitken basin is located at the lunar south pole. This is the second largest known impact basin in the Solar System, as well as the oldest and biggest impact feature on the Moon, [38] and should provide geologists access to deeper layers of the Moon's crust. It is where the Chinese Chang'e 4 has landed, on the far side.
Lunar south pole. Aitken (crater) The South Pole–Aitken basin (SPA Basin, / ˈeɪtkɪn /) is an immense impact crater on the far side of the Moon. At roughly 2,500 km (1,600 mi) in diameter and between 6.2 and 8.2 km (3.9–5.1 mi) deep, it is one of the largest known impact craters in the Solar System. It is the largest, oldest, and deepest ...
