I would have wanted to add something new but everything has already been said.
In my opinion if we put together post #22 and post #23 we complete the "puzzle".
Sun has satellites which have satellites of its own, so why can't the satellite of a satellite have a satellite? Consider this fact too: Sagittarius A* has our Sun as a satellite which has Earth has a satellite which has moon as a satellite.
with this the same question becomes meaningless...
When you think about it our moon probably has 1000s of mini moons.
As dust specs and tiny objects go are they really moons? and are they stable moons?
Moon definition also needs a new rule on what is a minimal thing to be called a moon.
some small asteroid can be everywhere...
