The South Pole–Aitken basin (SPA Basin, / ˈ eɪ t k ɪ n /) 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 basin recognized on the Moon. [1]
The formation of new craters is studied in the lunar impact monitoring program at NASA. [4] The biggest recorded crater was caused by an impact recorded on March 17, 2013. [5] [6] Visible to the naked eye, the impact is believed to be from an approximately 40 kg (88 lb) meteoroid striking the surface at a speed of 90,000 km/h (56,000 mph; 16 mi/s
The large and relatively young lunar impact crater Tycho taken by the Hubble Space Telescope. [1]This is a list of named lunar craters.The large majority of these features are impact craters.
Herschel (/ ˈ h ɜːr ʃ əl /) is the largest impact crater on the Saturnian moon Mimas. It is located on Mimas's leading hemisphere, centered on the equator at 112° longitude. It is named after the 18th-century astronomer William Herschel, who discovered Mimas in 1789.
Compared to other bodies in our Solar System, Earth's moon isn't particularly huge. However, its relatively small size belies one of its most interesting features, which is a colossal crater ...
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
The Schrödinger impact basin, one of the younger, large impact craters on the moon, is within a few hundred kilometers of the moon’s oldest and largest impact basin, Petro said.
Von Kármán is a large lunar impact crater that is located in the southern hemisphere on the far side of the Moon. The crater is about 186 km (116 mi) in diameter and lies within an immense impact crater known as the South Pole–Aitken basin of roughly 2,500 km (1,600 mi) in diameter and 13 km (8.1 mi) deep. [1]
