The demotion of Pluto was a political act by a supposedly scientific org, was a gratuitous and unnecessary action, carried out to belittle the US. IMHO of course. I'll stick with David Levy's view:
"To Pluto And Far Beyond" By David H. Levy, Parade, January 15, 2006 -- We don't have a dictionary definition yet that includes all the contingencies. In the wake of the new discovery, however, the International Astronomical Union has set up a group to develop a workable definition of planet. For our part, in consultation with several experienced planetary astronomers, Parade offers this definition: A planet is a body large enough that, when it formed, it condensed under its own gravity to be shaped like a sphere. It orbits a star directly and is not a moon of another planet. To Pluto -- And Far Beyond

Thank you. That's what Alan Stern basically says as well. And that works for me.

If that IS what works, then how many known planets ARE in our solar system?
