Callisto

(Jupiter IV)
(well-known Jupiter moon)

Callisto (Jupiter IV) is Jupiter's second largest moon and the second outward from Jupiter of the original four moons found centuries ago (Galilean Moons), but the fourth according to current knowledge. Its radius is 2410 km (0.4 Earth's, 1.4 Moon's), its mass is 1.0×1023 kg (0.018 Earth's, 1.35 Moon's), with a mean density a little less than twice that of water (considerably less than the Earth or Moon) and subsurface oceans are suspected. Callisto's orbital period is 17 days and it is tidally locked. Flyby observations of Callisto have been made by the Pioneer missions, Voyager, Galileo, Cassini, and New Horizons.
