Pluto needs to up its game and become GRAVITATIONALLY DOMINANT!!!

Yeah, but this is Mike Brown we are talking about. The Don of the "Pluto is not a planet" mafia.

That would be Planet 12 :)

Nah. It should have been grandfathered in as planet 9.

If you want to stand on tradition, planet 9 has to go to Ceres.

Yeah that's where 12 comes from. IIRC it was the 12th known "planet" when it was discovered, if you include spherical, gravitationally differentiated asteroids.

The air quotes are because by the geophysical definition of planet (the only scientifically reasonable definition, fight me) our Moon, the Galilean moons of Jupiter, and Titan are all also planets, and I think they were known at that time.

Our solar system likely contains thousands of planets. I wish people could get excited over that rather get stuck up about tradition and "how will kids ever remember them all?" My kids can name the stats and special powers of 350 Pokemon. They'll be just fine.
