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 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. [2] [3] The remaining structure, comprising the deformed underlying bedrock, is located in present-day Free State province of ...
The largest in the last one million years is the 14-kilometre (8.7 mi) Zhamanshin crater in Kazakhstan and has been described as being capable of producing a nuclear-like winter. [11] The source of the enormous Australasian strewnfield (c. 780 ka) is a currently undiscovered crater probably located in Southeast Asia. [12] [13]
The largest of these may have a hydrostatic-equilibrium shape, but most are irregular. Most of the trans-Neptunian objects (TNOs) listed with a radius smaller than 200 km have " assumed sizes based on a generic albedo of 0.09" since they are too far away to directly measure their sizes with existing instruments.
Lunar: 1,624 craters (31.2%) Venusian: 900 craters (17.3%) Mercurian: 397 craters (7.6%) Martian: 1,092 craters (21.0%) Others: 1,198 craters (23.0%) Distribution of named craters in the Solar System as of 2017. [a] This is a list of craters on Venus, named by the International Astronomical Union's (IAU) Working Group for Planetary System Nomenclature. All craters on Venus are named after ...
Geologically young belt of grabens that cut through craters. Bright, icy material exposed on canyon walls. Pluto: Sleipnir Fossa: 580 km (360 mi) 5-10 km ≈3 km (2 mi) One of the six extensional "spider" fractures, cuts through Tartarus Dorsa . Not yet officially named. Lowell Regio canyons ≈200 km (120 mi) 75 km (45 mi) ≈3-4 km
Mead crater is the largest impact crater on Venus, with a diameter of 280 km (174 miles). [1] The crater has an inner and an outer ring and a small ejecta blanket surrounding the outer ring. Mead crater is relatively shallow (likely due to viscous relaxation [2] and infilling) and crater floor looks very similar in morphology to the surrounding ...
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]
