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 628% of the body diameter (the circumference along a great circle).
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 one of the largest impact basins in the Solar System. "Calor" is Latin for "heat" and the basin is so-named because the Sun is almost directly overhead every second time Mercury passes perihelion. The crater, discovered in 1974, is surrounded by the Caloris Montes, a ring of mountains approximately 2 km (1.2 mi) tall.
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 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 ...
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).
It is 89% the mean equatorial diameter of 569 km (354 mi), making it one of the largest craters in the Solar System, and at 75°S latitude, covers most of the southern hemisphere. The peak in the center of the crater is 200 km (120 mi) in diameter, and rises 22.5 km (14.0 mi; 74,000 ft) from its base, [ 3 ] [ 2 ] making it one of the tallest ...
Odysseus is the largest crater on Saturn's moon Tethys.It is 445 km across, more than 2/5 of the moon's diameter, and is one of the largest craters in the Solar System.It is situated in the western part of the leading hemisphere of the moon—the latitude and longitude of its center are 32.8°N and 128.9°W, respectively.
