Defining "Planet"

beardoc writes "The Sydney Morning Herald is running a story today about a controversial proposal to define what size a planet might be - depending on what the final definition of how big a planet is, we could end up losing Pluto (at 2300 kilometres) to the status of "asteroid" or gaining three more planets - Quaoar, Varuna and Ceres."

  7. This is deeply troubling by WankersRevenge · · Score: 5, Funny

    As a representative one of the nine planets, I find this proposal deeply troubling, especially since there are not any other representatives from the other eight. Once a planet is classified as an "asteroid" or "floating piece of shit with gravity", it not only loses its prestige, but also, it cannot apply for federal grants, and hence, usually suffers a major economic blow. Laugh you may, but I've seen planets go from a heavenly body to a drunk spinning horizontal and finally distingrate into an asteroid belt in no time. We must support our planets because if we don't, then who will?

    With the discovery over the past few decades of the Oort Cloud and Kupier Belt, it seems obvious that there are tens, if not hundreds/thousands of Pluto-sized objects out there. Obviously, we're not going to name all 10,000 of these rocks "planets." But then again, Pluto has a special place in history as the last "great" planet discovery on the level of Uranus and Neptune

    Across the pond it is not considered to be on this level. Pluto is important to America, because it's the only solar planet discovered by an American astronomer. But in fact, it's not that important to anyone outside the USA. I guess this debate is pointless - if International Astronomical Union would ever dare to call Pluto a mere asteroid, George W. Bush would immediately call an airstrike on Institut d'Astrophysique in Paris, France (where those pesky European astronomers conspire against America). And no, he would need no stinkin' United Nations to approve this.
