What defines a moon? This article: is currenlty viewable at CNN Interactive's Science & Technology section.

Comments by astronomers claim that orbiting bodys, as small as a mile across, have been discovered. Not that I've ever really thought about what defines a moon, but isn't "a mile across" quite small to be defined as a moon. I guess if it orbits another body maybe it is one.

Think about it. The Jovian system, although part of Sol's family, is really it's own system, at least I have heard that description before. And if it is it's own system, then could we define some small moons as asteroids. Maybe defining a new term "Jovian Asteroid Belt".

Shape: I always thought moons were round.

Phobos & Deimos, Mars' moons, are not exactly the most spherical, and called moons by virtue of orbital servitude to Mars. Both bodies are not round.
