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).
This is a list of named craters on Callisto, one of the many moons of Jupiter, the most heavily cratered natural satellite in the Solar System (for other features, see list of geological features on Callisto).
[3] The central zone of Lofn (100–120 km in diameter) corresponds to the crater floor, which lies about 0.6 km below the surrounding cratered plains. Lofn is a shallow crater as compared to other craters of similar size. This is the main reason why it is called a flat-floored or anomalous dome crater. [2]
The largest, Ganymede, is the largest moon in the Solar System and surpasses the planet Mercury in size (though not mass). Callisto is only slightly smaller than Mercury in size; the smaller ones, Io and Europa, are about the size of the Moon. The three inner moons — Io, Europa, and Ganymede — are in a 4:2:1 orbital resonance with
Heimdall is one of the largest known impact craters on Jupiter's Galilean satellite Callisto, with a diameter of 210 km. It is located near the Callistoan south pole at 63°30′S 3°00′E / 63.5°S 3°E / -63.5; 3 ( Heimdall

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]
