Why Pluto Still Matters

StartsWithABang writes Nearly a century ago, Pluto was discovered, and for 48 years it remained the only known object whose orbit takes it beyond the gravitational pull of Neptune. In a single generation, we've now discovered more than 1,000 additional objects in the Kuiper Belt, but does that make Pluto any less special? Here's a strong argument for why Pluto might matter now more than ever.

Yes it made Pluto a planet but so what!?

    The definition they did accept in the end has a LOT wrong with it:
    It explictly mentions the sun so extrasolar planets aren't planets.
    It defines dwarf planet such that a dwarf planet is not a planet (very confusing especially for a definition intended for lay people).

      The problem is that "planet" was defined in ancient times as a wondering star; back then there were only 5 of them and so it was a clear-cut definition. Since then, the word has stuck but our knowledge has increased and so it's no longer trivial to decide what is and is not a planet. Thus, any definition will be controversial.

      I don't really agree with all your points, though, as I think they're rather nitpicky. For instance, we don't know much about extra-solar planets so it's ok to lump them into one class for now. The class has a descriptive name: "extra-solar planet", so we're good there.

      The Trojan Asteriods are in stable orbits created by Jupiter and the Sun. In effect, Jupiter has cleared its path as everything in its orbit is best thought of with respect to it. So Jupiter really isn't violating the spirit of the definition.

      It also makes sense to have "dwarf planets." When you look at what orbits the sun you have the inner rocky planets, the outer gas giants, the asteroid belt, the trans-Neptunian objects, and comets. The asteroid belt and the TNOs are known to contain members of substantial size and it's reasonable to call those members dwarf planets.

Including extrasolar planets in the technical definition of "planet" has just as much potential for confusion -- which is to say not much, but some. It's in the nature of language to be confusing without context. Including the Sun in the definition actually makes it more consistent with the classical definition of a planet -- a visible object that moves against the backdrop of the "fixed stars".

To me, it represented all the undiscovered mysteries, all that was still unknown, and the hope that someday, it might matter more. I was actually rooting, as a kid, for Pluto to be bigger than Mercury, simply because I wanted it to be more important in some measurable way. And because it took longer to orbit the Sun than everything else, because it was different from all the other planets in practically every way, I truly believed it was special.

    It’s been some thirty-odd years since I was that child, learning about Pluto for the first time, and in those same thirty-odd years, our estimation of the Solar System has grown to make it a larger, more well-known place. But in that same time, I’ve grown, too, and the most important lesson I’ve learned about Pluto—that I would have told my young self if I could—is this:

Ceres has the same issues as Pluto; it's the biggest asteroid but it's smaller or perhaps comparable to the combined size of all of the asteroids.

  26. Triton [Re:Sentimental nonsense.] by Tablizer · · Score: 1

    I'd argue that Triton (of Neptune) is currently the "most well studied known Kuiper belt object", being it already had a Voyager flyby. There's a good chance Triton is from the Kuiper belt based on composition, density, and its "backward" orbit.

    But we'll have better evidence for that theory either way when Pluto is visited by New Horizons.

    "atom" has a pretty well-defined meaning (if a little fuzzy in places; what's the difference between alpha particles and doubly ionized helium, for example?), and it's a useful meaning. "planet" has been fuzzy since we started finding asteroids. Certainly Venus is a planet. How about Ceres? Pluto? The moon? If we're going to use the term to mean something, we have to have some sort of definition, and we really should stick to it.

    I'd much rather see the apatosaurus renamed brontosaurus, myself.

    The decision was done "in the last few days" because they spent weeks at the conference talking it through with subject experts, after MONTHS of discussion over it before they agreed to meet. Why not go the whole hog and claim the decision was made in the time it took the IAU to state the result, about 10 seconds tops?

    The definition they rejected, geophysical, had far more holes in it.

    The definition you upbraid is far better than you claim BECAUSE YOU DO NOT UNDERSTAND IT. Jupiter OWNS its orbit. NOTHING ELSE in its orbit makes it give a shit about its location. Its orbit is decided by the sun and itself almost entirely.

    Pluto's orbit is definied by the sun, itself AND CHARON.

    See the difference? Or are you so all wrapped up in your americanexceptionalism that Pluto, being "found" by an american MUST REMAIN A PLANET!!!?

  29. Ceres *WAS* a planet by Anonymous Coward · · Score: 0

    Because, before then, they didn't see any of the other objects, therefore there was NO ASTEROID.

    When we found the others, Ceres became an asteroid and demoted. You didn't hear any baby whining and pouting over that because it wasn't fat-headed merkins putting their national pride in having "found a planet" then getting bend when it turns out not to be a planet because they found all those other similar rocks and demoted it.

    Just like Ceres.

    Which wasn't discovered by an american. So you don't care or know about it, right?

      Hey you're right. Venus, Mars and Jupiter were discovered by them there Geeks (or the Romance - whatever, they all wore skirts), so they can fuck off too.

      Hey, how come nobody spotted that?
