TO TRANSLATE FOR NON-SCIENTIFICALLY INCLINED SPORTS FANS: There was this player. He was for a while thought to be among the ELITE, one of the very very best. But then some folks were like, ehhh, he doesn't look like all the other Elites, he doesn't play in nearly the same league, his game is different. But the scales decidedly tipped when we found this other guy in his same league, who we thought was just as good or a bit better, and so we don't want to open the floodgates to everyone being elite, so we'll reclassifiy [read: demote] this guy as "dwarf elite.". Take a star away, right, you were just a four-star all along.
That's Pluto, right. Just a dwarf planet. Not one of the big boys. Not a planet. Orbit is way out of the planetary plane, shape of orbit is unnatural (dips inside Neptune's orbit), and then we discovered Eres in the Kuiper Belt which appeared to be bigger than Pluto, and we are sure there are lots more of them in the KB, so either we have dozens of planets or we just say Pluto and Eres aren't planets. We make up a new definition of dwarf planet, and it turns out not only are Pluto and Eres dwarf planets, but the largest asteroid Ceres (not a KBO) also meets that definition. And now we have only 8 planets and we're all set.
BUT: Then we saw the guy in a game up close, and we should all be like, dude, he's elite.
Did seeing that photo of Pluto from a couple days ago change anyone's mind? It did mine. It's a planet. I'm not sure how to define it, but I know one when I see one, and Pluto looks like a planet. Compare how it looks to Ceres (one of the other three dwarf planets). Ceres looks like a big asteroid, a huge rock, which it is. Pluto looks like a planet. Period.
Who's with me?
[And yes, I know the title is in error, it's in the Kuiper Belt, not the Oort cloud, but I was typing OOT and just couldn't resist.]
