and he sure isn't pleased with the iau. you're late. ready for this? ready as ever.t wait to hear what alan's got to say about pluto's demotion. stern: i think that the iau has confused people, because their definition produces such illogical results. what i really like is what i call the star trek test. when kirk and spock show up orbiting an object, just by looking at the picture of it, they know it's a planet. in an iau world, spock would have to come back and say, "captain, let me survey the entire solar system, "determine whatever objects are there. "i'll integrate the orbits overnight. i'll get back to you." it's not that hard. so you don't even care about whether a zone is cleared or some of these other parameters. no, that's all about location, and location is for realtors, not scientists. (laughing) i don't think it counts at all in terms of what it means to be a planet. tyson: so then, what is pluto? according to alan, it's not just a kuiper belt object. it's not a lonely oddball either, and it's definitely not demote-able. it's simply a new kind of planet,
