Pluto's demotion
Pluto was demoted today from planet to .... rocky annoyance? The International Astronomical Union (IAU) adopted a resolution on planet definition, and Pluto didn't make the cut.
There are people alive today who remember when Pluto was first discovered in 1930 ... can you imagine some old grandpa type saying to any young whippersnapper who comes along, "I remember when there were just 8 planets ... then there were 9 ... but it turns out we didn't define the term 'planet' sufficently enough so when we calrified it, it turns out there were 8 all along and just an imposter planet with its silly little moon that tried to come in as a sister planet for a while too. But we sure showed it. We defined the term planet and they never had a chance..."
Ok obviously my imagination has gone off the deep end. Pluto was my favorite planet ... in jr. high I managed to do two extra credit research papers on Pluto, even then there was a debate on if it was a planet or not. I wish they had managed to let Pluto keep its status. Now I don't know how to explain it. That extra bit of planetoidy rock with the satelite named Charon ... or Pluto the rock formerly known as a planet ...
The IAU now defines a planet as "a celestial body that is in orbit around the sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a ... nearly round shape, and has cleared the neighborhood around its orbit."
Can't science make up it's mind? At least with English we embrace the fuzziness of it all ... science was suppossed to be the hard-nosed, one answer for everything subject.
