− | + | The four {{w|Galilean moons}}—the largest of the 67 {{w|moons of Jupiter|moons orbiting Jupiter}}—have an unusual orbit, in that the three inner moons, {{w|Ganymede (moon)|Ganymede}}, {{w|Europa (moon)|Europa}}, and {{w|Io (moon)|Io}}, have an {{w|orbital resonance}} of 1:2:4, as illustrated in the picture to the right. This comic personifies the moons, with the "MOOOOOON!" interruptions representing the disruptions in their orbits created by the resonance. Io, Europa and Ganymede say "Hi!", "What's your name?" and "MOOOOON!" respectively, when facing Cueball. {{w|Callisto}}, the large crater-scarred moon, gets gradually tired of their antics and leaves to orbit Cueball. | |

− | + | Contrary to the comic, Ganymede, Europa, and Io never actually line up on the same side, but only in the same line on opposite sides (see animation). | |
− | The title text | + | The title text describes one of the moons (most likely {{w|Callisto (moon)|Callisto}}, the outermost of the four) escaping from the rest. "Their weird ... thing" ascribes a vaguely sexual nature to the other three moons' relationship, which is extra relevant due to the fact that all four moons are named after lovers of {{w|Zeus}} ({{w|Jupiter (mythology)|Jupiter}}'s equivalent in the Greek pantheon), who often held them captive, much as Jupiter the planet holds the four moons captive. |

− | + | <!-- If anyone's wondering, the genders used here for the moons (i.e., Ganymede being male and the rest being female) are not arbitrary, but rather represent their genders in Greek mythology. Since they're already being personified, using "he" and "she" instead of "it" just seemed to flow better. --> | |
