@tcn33 It’s not a planet unless Ceres, Haumea, Makemake, Eris, 2207OR10, Quaoar, Sedna, Orcus, 2002MS4 & Salacia are, too. +prob many more.

@kchangnyt@AlanStern@plutosgems Does everyone know how many rivers there are on Earth? But you can name the famous ones right?
@Spyder_Webb @AlanStern @plutosgems Just sayin’ Plutophiles aren’t out there chanting, “We want Eris and Ceres, too!"

@kchangnyt@AlanStern Of course Eris & Ceres are planets. As far as I'm aware a dwarf planet is still a planet. Is a dwarf human not human? -
