Ah! Can you post the citation? I think we should cite a source. > On the other hand, the IAU says Pluto is not a planet, so I don't know if > we can trust them anymore. :-). I've posted my own thoughts on that here: http://www.dwheeler.com/blog/2006/09/01/#planet-problems But I'm no astronomer, so I'm certainly not an authority on the topic.
