    If one more person asks me about the definition of "planet" ...

    Option 5.
    Is that just me?

    You think you've got problems... try being the guy who started and maintained Wikipedia's "Definition of Planet" article for eighteen months until it got on the news and suddenly everyone and his brother wants a piece of the action. I'm starting to get snarky.

    I chose #1. It is interesting and it beats watching baseball at the moment. In a few days, I will change my mind, however.

    It is bound to be 11pm over there, when do we get this over with? Ummm...I am asking only those who have not select no. 5, of course.

    Well, I'm baffled by the whole concept of competitive sport as well, so that one's too close to call, for me.

    I shudder to think.
    If I ever want to be hassled by single-issue maniacs with too much time on their hands, I'll write something for Wikipedia ...

    #1-#5: Decline discussion, maybe scream, even pass out from boredom couple of times, but after a few punches and kicks I will find myself entered in a lively debate.

    Actually, I'm baffled by the concept of non-competitive sports... like running by oneself. Unless it's a race, it's an activity, not a sport.

    Yikes, I was thinking it was all over today. Is there another week to go of this? You may need to add a 6th category by then.

    [I'll probably drift to the higher categories very soon; but, admittedly, I'm easily humored. ]

    I assume the question is "real" people asking, rather than all the "electronic" people around here talking about it.

    I picked # 1, though the couple of people who have asked me about it are more interested in my opinion (as someone interested in astronomy) rather than in debating me about it. I think it is great that a lot of people who otherwise would have no interest in astronomy are talking about such things.

    It is also much better than being asked about "Mars as big as the Moon" (I'm still getting asked about that)

    It is interesting and anything which gets more people involved and interested in learning about the wonders of the Solar System can't be a bad thing. Is it really a problem if the number of planets should rocket exponentially!

    Definitions have never been simple concepts to convey, after all language is ambiguous, what one person says to another can be totally misinterpreted,
    after all a definition to a word simply provides a whole new list of other words to add to the confusion!
    Hence the fun in debating the variables that consititute bestowing Planet-hood.

    Wow. The BA's blog mentioned the earliest would be today, but did mention it ends next thursday. I checked the IAU schedule, briefly, but did not see a set day for a decision.

    Are Plutophobia, planaphobia, or celestial taxaphobia wiki words yet?

    IAU Planet-Definition Press Release

    The draft "Planet Definition" Resolution will be discussed and refined during the General Assembly and then it (plus four other Resolutions) will be presented for voting at the 2nd session of the GA 24 August between 14:00 and 17:30 CEST.

    I'll debate it, but only because I largely stayed out of the debate for the past year. Around these parts, the definition of a planet has been seemingly the most religious thing that Phil's ever let us discuss. After a few days it seemed pointless to keep adding my voice. I did, however, absorb some ideas and expand my own opinion on the issue by reading through what felt like thousands of posts.

    I voted scream but if one more person does another South Park-eque "but what about the children!" rant I'll definitely be moving up to punching status.

    Further discussions will be needed in the future, as the current definition, though adequate for the moment, is less than perfect. I for one could discuss it forever... [enters into a lively debate]

    Hey, I went to a prize fight and a Texas Ranger baseball game broke out! No respect, I tell you!

    Actually the five game series between the Bosox and Damn Yankees that starts shortly should be a classic. Go Beantown!

    About the poll, I voted 1 (fixes tie)...

    BTW, the definition seems OK except that they don't really specify what they mean by "roundness". There should be some kind of tolerance. ASME Y14.5M-1994 (Dimensioning and Tolerancing) has a definition for sphericity (this is what should apply to a three-dimensional body, roundness (circularity) is a two-dimensional tolerance) that allows for deviations from the nominal. Perhaps something like that should be adopted by the IAU.

    Criteria like shape are rigorously meaningless, since from a topological point of view all bodies in the solar system can be mapped to a sphere.

    I chose number one, but then I carry on live and vigorous debates with Mr. Schlimple the man that lives in my left pointy finger. He's a riot.

    It all reminds me to go take a look at the Astronomy picture of the day

    Yes, I heard about that. The pitcher supposedly shouted "Pluto!" during the pitch.

    Or a cube.

    Tough break in game 1. The Beanies better do better in Game 2 or it may be a long weekend.

    Also voted for option 1, mostly because no one has asked me about it (few co-workers/friends care much about astronomy, sadly)

    I actually hugged a man today (a rare event in the life of an introverted heterosexual Scot, believe me).

    A coworker came up to me and said: "You're interested in astronomy, aren't you?"
    "Ye-e-es," I allowed, slitting my eyes and clenching a preparatory fist.
    "So is it true you can see the International Space Station? How could I see that? My kids would love that."
    (Followed by: "Aaaargh! Get off me! What are you doing?")

    That sounds like me, in real life. I assume you are also.....Plutonic?

    All that for the ISS? What would you get for an Iridium flare?

    Fortunately Y14.5 doesn't take that approach and deals with the actual surface profile, which then would have to fit between two coaxial spheres separated by the amount of the sphericity tolerance. See ASME Y14.5M-1994, paragraph 6.4.3, or here for more information.

    Thanks.

    I was little bit facetious in my remark, but I really do think shape shouldn´t be taken into account. Sphericity as a citerion for planethood seems to be introduced just to provide some sort of psychological comfort (Earth itself is not a sphere, rigorously).
