I'm only down with the "Pluto is a planet" crowd, if they rep Ceres and at least one of the others (Eris, Hamuhea, Makemake, or one of the others I forget) too.
So there's no version of the solar system where there's only 9 planets. It's 11+ lads.
Yeah, people don't realise that removing Pluto is the conservative choice when it comes to the list of planets.
It was the only choice if we are expecting elementary students to memorize them all in order.
Eros na gonya be on dis list no more, pampaw
Eros Venus now, sasa?
If Sol has a ring now, is it married?
The more the merrier
I'd be happy with:
Pluto = planet
Anything smaller than Pluto ≠ planet
Nine planets. Now with clear non-stupid rules.
The arbitrary cutoff size being to ensure continuity of the scientific consensus in popular awareness when I was a child isn't a stupid rule.
Not even when a larger kuiper belt object is found.
Not even, when since mass is the primary means of estimating size until we fly a probe out there, we estimate a smaller but much with much more mass object to be larger and we debate a 10th planet yet again.
Hey, if we find something bigger than Pluto, then by all means let's call it a planet.
By any reasonable person's definition of a planet, Pluto is a planet. It's a rocky spherical mass that orbits the sun, with a varied terrain of mountains, plains and glaciers. It has days and seasons. It has its own system of moons.
An additional grievance I have is that, by the IAU's stupid definition of a Dwarf Planet, Charon should really be called a dwarf planet too. It isn't a satellite of Pluto in a meaningful sense - both Pluto and Charon orbit a point between them. The other moons also orbit this space between Charon and Pluto.
So, want to know why it isn't a Dwarf Planet? Because the IAU class it as a planetary satellite. What's the formal definition of a planetary satellite then? There isn't one. It was discussed, but a formal definition was not decided upon. Charon is literally a moon now because it was called a moon before the definition of a planet was changed and dwarf planets were invented.
I'm all for formal definitions, but the IAUs current rules are just really sloppy. It's maddening.
