- Well, that's nice, but you might want to check the astronomically accepted
- definition instead. And just how do you propose to define origins here?
- Do you mean a body that coalesced from the primordial solar nebula at a
- mean distance of between 1.4 and 5.2 AU from the center of that nebula?
- How would you propose to show where all such bodies were now, or even if
- the main belt asteroids all started out there?

- So who the heck are you? President of the International Astronomical Union?
- When Charlie Kowal discovered Chiron it was classed as an asteroid, and it's
- orbit takes it well past Saturn. Yes, Chiron now appears to contain more
- volatiles than "typical" asteroids but so what?
