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?

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 :-)
