Has Rick & Morty taught us nothing!!!

Of course in reality it makes not a blind bit of difference, nothing changes. Planet or not is still the same object.

The geology issue is significant. "For example, Pluto has an underground ocean, a multilayer atmosphere, organic compounds and evidence of ancient lakes and multiple moons. According to Metzger, the only planet with a more complex geology than Pluto is Earth." [UCF Release]

Huh - once again with the "Identity Planets", and excluding one because it might "open the floodgates for hundreds of trans . . ."
Can't we all just be accepting of our differences and get along?

Dwarf planets got nobody...

Its a dwarf PLANET. That's a PLANET. No need to get emotional about how they don't feel that's cool enough. There really is no requirement for all the drama

Then there is the problem of a rogue planet.

I'm glad that somebody is standing up for Pluto's rights! I was devastated when Pluto was relegated to second class planet status. And the fact that the other bodies that match the round definition but should be called moons is self evident; moons orbit planets, not stars!

If it's in the same PLANE as the rest of the PLANets (think French - plan-ay) then it's a plan-et. That old story about the word "planet" being some ancient Greek for "wanderer" is BS to cover up the fact that ancient people were smart enough to see everything was revolving in a PLANE. If it's been traditionally recognized or named as a God, it's a planet. If it's been traditionally recognized as a planet, then it's a planet. Nobody can "kick a planet out of the planet club". Everyone still calls Pluto a planet. But here's one concern: From Wikipedia (where else? Why go to college when there's Wikipedia?): "Its orbital path doesn't lie in the same plane as the eight planets, but is inclined at an angle of 17°. Its orbit is also more oval-shaped, or elliptical, than those of the (other) planets." So this Plane-t isn't in the same plane - well, not exactly anyway. But guess what? Neither are the rest in an EXACT plane. So someone's gotta make a decision here. And as The World's Leading Authority (a big job, take it from me (which is redundant)), I am that "someone". Planet? My decision? Yes, and it slid thru on the basis of also having been named after an ancient God. Not to mention a non-human Disney cartoon character. And because "everyone knows" Pluto is a planet - within 17 degrees of the plane - close enough! Now, what about kicking Astronomers who don't like Pluto out of the Astronomers' club? Hmmmm? Let's take a vote on that!

Since "plane" is an English word, and the ancient Greeks did not speak English - a language which they predated by some 1500 years - it's your version of events that is unfortunate BS. The word "planet" comes from "asteres planetai", the Greek for "wandering star". You can trace it through writings all the way back to antiquity. The evidence is there, if you care to research it.
And no planetary scientist identifies orbiting in or near a specific plane as being a requirement for planetary status. It's a red herring.
