Although I guess I’ve come to terms with Pluto being demoted, if we’re going to make it a planet again, rather than contriving some set of rules whereby Pluto gets to be a planet but Ceres doesn’t, make Ceres a planet too. (What the heck, it used to be a planet.)
One concern I saw expressed at the time about the idea of designating Pluto, Eris, et al. as full planets is that we’d wind up with dozens and dozens of planets (Mercurcy, Venus, Earth, Mars, Ceres, Pallas, Vesta, Jupiter, Saturn, Uranus, Neptune, Pluto, Eris, Makemake, Quaoar, Sedna, Orcus, Ixion, Varuna…)
To which I say, bring 'em on! I think it would be shiny to live in a Solar System with 40 or 50 planets.
