Pluto is not, nor ever should be classified as a planet.  It is smaller 
than some 'asteroids' and KBO's (Kuiper Belt Objects), 2003 UB313 and 
Sedna for example.  I went to a very illuminating lecture on this at the 
UK Astrofest this year, and Dan Green made a very convincing argument.  
His explanation can be found here: 
http://cfa-www.harvard.edu/cfa/ps/icq/ICQPluto.html  Unfortuantly, he 
hasn't included the graph he put up during the lecture which makes it 
clear as day that Pluto cannot be a planet really, and I can't find it 
elsewhere on the web.

So, in my opinion, it is a KBO... 

Mind you - we all have to bow to the IAU in this matter, and they are 
including other KBO's and large asteroids simply to justify Pluto's 
position as a planet....

Nevermind, eh?
