Pluto Decision Meets with Frustration

But only 10% of them voted this afternoon.'" On a less serious note, lx writes "Nonplussed by Pluto's recent downgrade from Planet Status, Fox News's own John Gibson does an incredible Stephen Colbert impersonation to correct the 'revisionist history' of the IAU's decision.

      Why? Well, first of all it's a lot of fun to argue about stuff like this--and I never could resist a good argument. It's too bad, though, that the astronomers turned this question into a pissing contest--shows they don't know how to have a proper argument. A vote, for cryin' out loud! Now if you want to see the fur fly with panache, call in the philosophers.

      Seriously, there are some interesting astronomical questions that are brought up by this "is Pluto a planet?" debate. When Clyde Tombaugh discovered Pluto, astronomers were expecting to find another planet, because there were some irregularities in the motions of the known planets that could only be explained by more mass out beyond Neptune. So when Tombaugh spotted Pluto, everyone shouted "hurray", the problem was solved, and we had nine planets. Only it wasn't quite solved--Pluto didn't have enough mass to really account for all the observed perturbations. Well, at least that's what I remember reading about Pluto...feel free to correct me if I'm wrong.

      Eventually, I think astronomers--and normal human beings--will come to a consensus, and I believe that consensus will indeed confirm Pluto's debasement. Like the guy in one of the articles said, Pluto just isn't that big, so if it qualifies for planet-hood, then a lot of other rocks do too. Clearly, that would get too confusing--it was bad enough just having to remember nine planets...think of the children!

      One thing that makes this such a productive argument is that it forces us to acknowledge that the solar system is a more complicated--and vastly more interesting--place than we thought. I think that's a good thing...even if it means the last true thing I learned in school has just gone down the tubes.

      I'll tell you what, though--while we're cleaning up astronomical nomenclature, let's do something about The Unmentionable Planet--you know the one just this side of Neptune, which was discovered to have rings around it. Ever since that joke went around, no one has been able to say--or even think--the name without dissolving into a fit of hysterical laughter. My personal favorite solution is to Greek-ify the spelling and pronunciation a bit to render it harmless: maybe "Ouranos".

      Two things really bothered me about this decision, and neither of them are the decision that Pluto is not a planet, but have to do with the way the decision was made.

      1) When asked about applying this definition to other stars and their potential planets, the committee that proposed this definition said that the definition on the table only applies to our solar system.

      2) One of the delegates said, "We would really look like idiots if we came out of this meeting without some type of decision." (I don't know who to attribute this to, but I heard the scientist's voice on NPR).

      Another interesting tidbit is that the original defintion, as suggested by the committee, had the unintended consequence of removeing Neptune from the definition of a planet (it hasn't fully cleared its neighborhood, i.e. Pluto), so they added an addendum to the definition.

      My thought is the IAU does look like idiots, for doing 1, and making statement 2. All they have done is muddy the waters again. They haven't come up with a definition that will be applicable to all bodies orbiting any star (even though there are bound to be exceptions). The addendum to make Neptune a planet under this new definition again shows that they really didn't think this through like they should have before submitting the definition.

      If they were to act more like scientists than media-coverage hungry people (the "we would look like idiots" comment), they might have actually come up with a definition that didn't need an addendum to include a large gas giant, and one that would be applicable to extra-solar planet hunters...

    (1) A "planet"1 is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.

    There are several problems with (1). In particular:
    • Extrasolar planets are no longer "planets" since they don't orbit the Sun.
    • Jupiter is not a planet, because it has not cleared the neighborhood around its orbit - it has asteroids at the Trojan points.
    • Earth is not a planet, because it has not cleared the neighborhood around its orbit -- there exist Near-Earth asteroids and Earth-crossing asteroids. (One might argue that this is getting worse, what with all the space debris we keep flinging into near-Earth solar orbit).

    (2) looks OK, but the IAU folks have taken the (IMHO) insane view that a "dwarf planet" is not a subtype of "planet" at all (contrast "dwarf pine tree" or "dwarf sunflower" or "dwarf hippopotamus", all of which are subtypes of their source nown). That destroys a potential way to finesse the Pluto issue -- by calling it a dwarf planet, they could have let everyone have their semantic cake, and eat it too.
