Reposted from my twitter, because this “OMG Pluto is a planet again!!!” thing is really making me angry.
First of all, just because astronomers at Harvard decided that Pluto should be a planet again doesn’t make it official. As of right now Pluto is still not recognized as a planet by NASA or the IAU.
The major issue here is that Pluto is currently categorized as a dwarf planet. A dwarf planet is different from normal planets in that it is unable to clear other objects out of its orbital path due to its small mass.
The problem is, dwarf planets seem to be increasingly more common as more and more are discovered. There are at least a dozen, maybe even up to 200 dwarf planets in our solar system. If Pluto becomes a planet again, then what are we going to do about the other dwarf planets? Do they get to be planets too? Having more than 200 planets in our solar system to memorize might get a tad confusing.
And yet, people are willing to promote Pluto back up to “planet” status simply because they are attached to it and find the “little guy” endearing. That’s not very fair to the other dwarf planets, is it?
This is what bothers me so much about this debate. Pluto was demoted for a reason. It just doesn’t fit in with the other planets. I know many people are willing to make some sort of story about this, saying that Pluto will finally have reached “justice” or “gotten revenge” or something like that. But if you ask me, Pluto was out of place ever since it was discovered in 1930. But it found a proper family with the other dwarf planets, it found a place where it could truly belong. And if you people are so eager to accept Pluto as a planet again, then you had better be willing to accept Pluto’s brothers along with it.
