Tales of the Heliosphere

Eris is an icy dwarf planet that isn't a real planet because a convention of scientists decreed it so. Although Eris is a dwarf we now know it's more massive than Pluto. It's actually about as massive as all the asteroids combined. Here's some more interesting information about Eris the planet that's not a planet. It's round, it's got an atmosphere albeit a frozen one, it's own tiny moon, and a rocky surface. It also revolves around the Sun not around something else. So, it's not a moon. (Here.) That sounds a lot like a planet to me.
