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 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.
Valhalla is the largest multi-ring basin on Callisto and in the Solar System (with diameter up to 3,800 km). [4] It was discovered by the Voyager probes in 1979–80 and is located on the leading hemisphere of Callisto, in its Jupiter facing quadrant slightly to the north of the equator (at about 18°N latitude and 57°W longitude).
The North Polar Basin on Mars is speculated by some to be evidence for a planet-sized impact on the surface of Mars between 3.8 and 3.9 billion years ago, while Utopia Planitia is the largest confirmed impact and Hellas Planitia is the largest visible crater in the Solar System.
This is a list of officially named craters in the Solar System as named by IAU's Working Group for Planetary System Nomenclature.As of 2017, there is a total of 5,223 craters on 40 astronomical bodies, which includes minor planets (asteroids and dwarf planets), planets, and natural satellites. [1]
The huge indent, called the 'imbrue basin,' stretches across 750 miles.
The landscape has since been eroded to a depth of around 7–11 km (4.3–6.8 mi) since formation, obliterating the original crater. The remaining structure, the "Vredefort Dome", consists of a partial ring of hills 70 km (43 mi) in diameter, and is the remains of the central uplift created by the rebound of rock below the impact site after the ...
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.
