Re: [GZG] No more pizzas!



Actually, unless the press has grossly misquoted the wording of the definition, Earth and Jupiter aren't planets either. The plank of it that demoted Pluto is, they have to "clear the neighborhood of space around their orbit" to be a full planet.

If that's the definition, even _Jupiter_ isn't a planet. What's the count on trojan asteroids sharing its orbit now, fifty thousand? You heard it here first, folks, Jupiter has been redefined as a "dwarf planet". Awesome stuff.

(I really hope that SPACE.com and the regular media have left something critical out as to what "clearing the neighborhood" means, because my understanding is that at least four of the eight "planets" left behind share their orbits with numerous asteroids. So I'm not sure at all what about that is supposed to apply to Pluto and not Earth, Mars, Jupiter, and Neptune.)

It's official, Pluto is a 'dwarf planet', and no longer a planet. Dozens of
mnemonics must be re-written.


US public radio reports that Pluto is unavailable for comment; I'm more
concerned about the owners of www.nineplanes.org...
