This drawing shows the positions of the four Galilean satellites relative to each other, and the path of the Galileo spacecraft on one of its flyby's past Jupiter.
Of the four Galilean satellites, Io is the inside moon, Europa the next closest to Jupiter, Ganymede the third furthest out, followed by Callisto as the furthest from Jupiter.
