    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.

  3. Vredefort impact structure - Wikipedia

    en.wikipedia.org/wiki/Vredefort_impact_structure

    The Vredefort impact structure is the largest verified impact structure on Earth. [1] The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed.

    The outermost ring was identified using seismic reflection data. It is up to 130 kilometers (81 mi) from the crater center, and is a ring of normal faults, throwing down towards the crater center, marking the outer limit of significant crustal deformation. This makes it one of the three largest impact structures on Earth.

    en.wikipedia.org/wiki/Impact_crater

    An impact crater is a depression in the surface of a solid astronomical body formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, [2] impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. [3]

    Following are the largest impact craters on various worlds of the Solar System. For a full list of named craters, see List of craters in the Solar System. The ratio column compares the crater diameter with the diameter of the impacted celestial body. The maximum crater diameter is 157% of the body diameter (the circumference along a great circle).

    The crater depth is 7,152 m (23,465 ft) below the standard topographic datum of Mars. [1] Hellas Planitia / ˈ h ɛ l ə s p l ə ˈ n ɪ ʃ i ə / is a plain located within the huge, roughly circular impact basin Hellas [a] located in the southern hemisphere of the planet Mars. [3] Hellas is the fourth- or fifth-largest known impact crater in ...

    en.wikipedia.org/wiki/South_Pole–Aitken_basin

    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]
