Random thought:
Planets revolve around the sun and moons revolves around whatever planet they belong to, but what would you call something that revolved around a moon? Is there even such a thing?

Considering that the revolving has something to do with gravity, I'd say that such a something would revolve around the corresponding planet rather than its moon.

Yes, yes - but then, why do moons revolve around planets instead of the sun? Besides, I was not so much wondering whether it would be possible, more what it would be called...

A satelite?

Isn´t that just the general term for things revolving around things?

*shrug* Yup, it was all I could think of. LOL

satellites

Objects revolve around the closest and strongest center of gravity. The center of gravity is determined by weight. If an object was close enough to a moon then the distance to the moon's center of gravity would draw it into the moon's orbit rather than into the planet or the sun's. Any object smaller than a moon that is drawn into orbit is called a satellite.
Hope that helps!

Yeah, it helps - though I was sort of hoping that the astronomers had some really cool word for it, that they were keeping secret from the rest of the world. But anyway, thank you :-)
