I remain convinced of what I said in 1999: if you are going to call some things "planets" at all, it must be on the basis of their being above some size -- and since that size is ultimately entirely arbitrary, let's set it at some figure that (just barely) lets Pluto retain its historical status that everyone's used to, while not letting a lot of smaller riffraff join the club. 2000 km seems the perfect figure for this purpose. Then -- for the sake of everyone's sanity -- let's DROP THE SUBJECT.
