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

@kchangnyt @plutosgems And they are planets too. Better get used to lots of small planets. Just like small stars.

@AlanStern @plutosgems Don't think most people ready to hear, "We have no idea how many planets. We'll never find them all."

@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 @Spyder_Webb @plutosgems I am. I’ve been on record for that since well before IAU-2006.

@AlanStern @Spyder_Webb @plutosgems In 2000 paper with Hal Levison, you call Earth (& Mars, Mercury, Venus) dwarfs. And Pluto is subdwarf!

@AlanStern @Spyder_Webb @plutosgems And the "clearing the neighborhood" concept comes from *your* paper!! http://www.boulder.swri.edu/~hal/PDF/planet_def.pdf …
