Saturn's moon Mimas -- Mimas is a moon of Saturn that was discovered in 1789 by William Herschel. Mimas' low density (1.17) indicates that it is composed mostly of water ice with only a small amount of rock. Mimas' most distinctive feature is a colossal impact crater 130 km across, named Herschel after the moon's discoverer. Herschel covers almost 1/3 of the diameter of the entire moon; its walls are approximately 5 km high, parts of its floor measure 10 km deep, and its central peak...

Jupiter's Moon Callisto -- With a diameter of over 4,800 km (2,985 miles), Callisto is the third largest satellite in the solar system and is almost the size of Mercury. Callisto is the outermost of the Galilean satellites, and orbits beyonds Jupiter's main radiation belts. It has the lowest density of the Galilean satellites (1.86 grams/cubic centimeter). Its interior is probably similar to Ganymede except the inner rocky core is smaller, and this core is surrounded by a large icy...
