Should all instances of moons be included as appearances? If so, then most works would be included- every single work with Yavin IV (which are numerous), every screenshot of a moon would qualify.

And even if the WORD moon was the requirement, the list would still be massive. There are more moons than Force-users, and it is likely that every media which includes at least one planet would have a moon. (The list of appearances of the Force states, "nearly every work." This list would likely be EVERY work.)
