I propose a simpler explanation for Ganymede saying "MOOOOOON!". Europa has asked Ganymede the same question, "What's your name?", every time they go by each other for eons. Ganymede is yelling the answer before it is even completely asked, exasperated at having to repeat it for the umpteeen gazillionth time.

Ganymede interrupts Europa, reminding me of the knock-knock joke, "interrupting cow," "interrupting cow wh..." "MOOOOOO". Ganymede is an interrupting moon. ~~charles
 
  
 
Maybe moons converse with Cueball, not between them itself?

Did someone change the animation? Because when I watch it, they all line up on the right side.

:Not the animation I've been seeing.  Starting at an arbitrary point:
 
:Io@12, Europa@12, Ganymede@3 (I+E Conjunction)
 
:Io@8, Europa@10, Ganymede@2 (I+G Opposition)
 
:Io@12, Europa@6, Ganymede@12 (I+G Conjunction, E Opposed)
 
:Io@4, Europa@2, Ganymede@10 (I+G Opposition)
 
:Io@12,Europa@12, Ganymede@9 (I+E Conjunction)
 
:Io@8, Europa@10, Ganymede@8 (I+G Conjunction)
 
:Io@12, Europa@6, Ganymede@6 (E+G Conjunction, I Opposed)
 
:Io@4, Europa@2, Ganymede@4 (I+G Conjunction)
 
:...then repeat
 
:That's one cycle of Europa and Ganymede, two cycles of Io and Europa (relative to each other, alone) four cycles of Io and Ganymede (likewise).
 
:There are two 'in-line' conditions, when Ganymede is in conjunction with one of the other moons, the remaining one in opposition, with Ganemedes other Io conjunctions having Europa off at an angle and the other Io/Europa conjunctions having Ganymede off at a right-angle.  If I've managed to note all that down correctly. (Note, this is nothing to do with the following plot regarding the XKCD motions, which I quite admire!) [[Special:Contributions/141.101.99.229|141.101.99.229]] 08:09, 7 December 2013 (UTC)
 
 
Hard to tell exactly which moon was which, until I plotted their cyclic orbits.

"You may also notice at the animated picture that, unlike in the fifth and ninth panels of the comic, the three moons are never on the same side of Jupiter at the same time." The animated picture doesn't match this text. In the animated picture it looks like the three moons are on the same side of Jupiter at least twice for each cycle of Ganymede. --

:It means they are never lining up on the same side of Jupiter. [[Special:Contributions/108.162.231.53|108.162.231.53]] 23:53, 7 December 2013 (UTC)
 
:That picture, which is very helpful, confirms that the three moons are all in conjunction with each other in panels 5 and 9 of the comic.  In the animation, Io and Europa have their conjunctions at 12 o'clock, so (if the comic were correct) this picture would imply that Ganymede should sometimes also be at 12 o'clock during an I+E conjunction.  In fact, the animation shows that Ganymede is always at either 3 o'clock or 9 o'clock during an I+E conjunction.  --[[User:BlueMoonlet|BlueMoonlet]] ([[User talk:BlueMoonlet|talk]]) 18:25, 12 December 2013 (UTC)
 
 
Also note that "Io" looks like "Lo" in many fonts, so Io saying Hi is a probably a little Lo-Hi (Low High) pun. And Io passes 10 times, a Io-10 pun. And Europa saying "what's your name" is maybe a pun on Europa sounding like "You Are" a bit? [[Special:Contributions/108.162.231.244|108.162.231.244]] 14:42, 10 December 2013 (UTC) Martin.
 
 
  
;Animation is correct
 
Randall's Moon Meetings are just a part of the joke, all four Galilean Moons never would meet in that way in reality. Randall does not present science publications here, but just comics, playing with real things. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 22:28, 12 December 2013 (UTC)
 
  
Is it possible that a person having moons is a reference to Ioun Stones? {{unsigned ip|162.158.38.214}}
