Don't worry Pluto, you're still a planet to me.

Interesting & informative. An excellent video.

@ToaStormu I!
-
@TheGamerer13 you got closer but there is 700000 in the kipper belt
-
Pluto should still be a planet! Anyone who agrees say I!
-
Well then I guess we have about 100000 planets in the kipper belt
-
I think, to rebel, we should take a vote and declare that the sun is not a star. Then it won't be one anymore and see how they like it.

@BreakWatcher No that's not the reason at all. Not even close, y would it be kicked out because it hass a smaller mass than others, dumbass. It's kicked because they found more planets like Pluto, so they kicked Pluto out with the rest of the new discovered planets.

@illwing About the barycenter, I thought Pluto was unique in that its barycenter with Charon is outside of its surface. IIRC, only Pluto has this characteristic - all other planets' barycenters are well inside their host planets' surfaces, no? Anyway, that was the point I was trying to make.

@christianready Right. Any two objects orbiting one another will have a barycenter somewhere, but Pluto and Charon orbit a location that's above Pluto's surface. For a while astronomers proposed that it made Pluto a binary planet.
