Callisto is a large, icy, dark-colored, low-density outer moon of Jupiter that is scarred with impact craters and ejecta. It has a diameter of about 3,000 miles (4800 km), the second largest moon of Jupiter, roughly the size of Mercury. It orbits Jupiter at a mean distance of 1,170,000 miles (1,883,000 km). Its mass is 1.08x10 23 kg. It takes Callisto 400.5 hours to orbit Jupiter. Callisto was discovered by Galileo and S. Marius (independently) in 1610.
