South Pole–Aitken basin - Wikipedia 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
What is the South Pole-Aitken Basin? - Science@NASA The South Pole-Aitken basin (SPA) is the Moon’s largest impact feature, named because it spans the territory from the small Aitken crater to the Moon’s south pole, or nearly a quarter of the Moon's surface
The Biggest Crater on The Moon Is Much Bigger Than We Ever Realized The South Pole-Aitken basin covers nearly a quarter of the Moon's surface, with a diameter of some 2,500 kilometers (1,550 miles) It's not easy to study the South Pole-Aitken basin It's over 4 billion years old, and huge; in addition, time and subsequent impacts have done much to obscure it
South Pole–Aitken massive impact 4. 25 billion years ago revealed by . . . As the largest and oldest well-preserved impact structure on the Moon, the South Pole–Aitken (SPA) basin on the lunar farside is critical for understanding early solar system dynamics and lunar history, but accurately determining its age remains challenging
The South Pole-Aitken Basin: Unraveling the Mysteries of the Moons . . . Spanning about 2,500 kilometers (1,550 miles) in diameter and reaching depths of up to 13 kilometers (8 miles), the South Pole-Aitken basin is an immense structure located on the far side of the Moon, extending from the south pole to the Aitken crater near the equator
The Moons largest impact basin | Lunar Reconnaissance Orbiter Camera Topographic data from LOLA can also help to give a sense of the enormous effect the SPA impact had on the Moon - the basin is more than 8 km (5 miles) deep A preliminary monochrome mosaic of the Moon from the LROC Wide Angle Camera (WAC), centered in the middle of the South Pole-Aitken basin
