  •  So then, your definition of "planet" is "rock" of (1+ / 0-)
    Recommended by:

    a certain size that is stable at an arbitrarily defined temperature.

    There's a lot of talk these days about extrasolar "planets."

    Maybe they'll turn out to not be planets at all.

    So maybe a good definition of planet would consist of "object that is stable at 273.15K with a mass at that temperature that is higher than x," where x is found by taking the mass of elements heavier than fluorine in the periodic table that is at least equal to the planet Mercury.

    There's nothing political or arbitrary in that definition, eh?

    You would make a great autocrat, I think, although from what I see, for a comedianne you might have to command some laughter and define the places where one is supposed to laugh.

    You remind me of one of those English teachers I had in high school who had a conniption whenever people used double negatives.

    "You don't know about me without you have by the name of The Adventures of Tom Sawyer but that ain't no matter."

    That Twain weren't no good speaker of English, and Pluto ain't no planet.

    •  I have no idea what you're talking about (0+ / 0-)

      in that last part. We're just talking here you know. I'm not dictating anything to anyone. You are misreading my tone. I'm not having a conniption, I'm not upset or angry or excited. We're just having a conversation where I am offering counter examples. Nothing more. People tend to project their unresolved issues onto others an awful lot on the internet. A little self introspection goes a long way.

      Anyways... I haven't looked up the definition of planet but I'll accept whatever the official definition says they are. It's just an opportunity to talk about these things. Officially Pluto is a dwarf double planet, two large bodies in orbit around each other with two (maybe more) small moons orbiting them. My opinion is that the original decision to demote Pluto from it's planetary status was the correct one and that re-designating it as a dwarf planet was a political compromise.

      You're welcome to disagree.

    •  my definition (0+ / 0-)
      1. The object is subject to gravitational self rounding.

      forming a spheroid with an eccentricity ratio of less then 0.1

      1. object maintains an atmosphere or did at one time.
      1. Object orbits a star not another planet
      1. orbital plane in the ecliptic
      1. has a satellite
      1. Mass sufficient to influence another planets orbit.

      require 4 of 6 or so.
