Moons of Jupiter

This lithograph shows Jupiter's four largest moons in their correct scales, in order of increasing distance away from Jupiter (from bottom: Io, Europa, Ganymede, and Callisto). All the images were taken by the Galileo spacecraft, except for the globe of Callisto, which was taken by the Voyager spacecraft. The accompanying text describes the images, provides some historical facts and statistical data, and lists some important dates in Jovian exploration.
