[meteorite-list] 'Plutons' Push Planet Total Up To 12

[tracy latimer]

For my utterly uneducated OPINION, maybe we should look at the effect a 
proposed "planet" has on the rest of the stellar system, via gravity.  That 
way, dim massive bodies don't get overlooked for bright tiny icy ones.  
Rocks that are largely, well, rocks could be called "asteroids", ones that 
are largely icy "Plutons" or "crutons" :), and ones that get perturbed 
towards the inner stellar system could either be called "comets" or "major 
disasters", depending where they are heading.  Planetary systems that orbit 
each other, rather than the Sun, can be considered in common, as would be 
the Earth-Luna system, or Pluto-Chiron.

An arbitrary cutoff could be established, and varied depending on the system 
thus studied, but I can hear the Europan Confederation howling right now!
