helplessselfish asked: So Hank, what's the deal with Pluto right now? Is it a planet or not?
Pluto is not a planet. The IAU (in my book) gets to decide what the definition of a planet is because there has to be a definition and they are by far the most qualified body to define it.
Pluto does not meet that definition, and thus should not be considered a planet. I agree with their definition, but even if I didn’t I would submit to it because I am not an expert.
Recently, three people sat in a room and argued about whether pluto was a planet. The audience then voted…and they voted that Pluto was a planet. That, of course, means nothing. If you want random groups of people to define scientific terms…it’s going to be hard to get any actual science done.
