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.

A satelite?

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...

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

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 :-)
