Because planet has strong connotations and our language. No one would care about Pluto weren't it given the title of Planet. Few normalfags have even heard of Haumea.

Yeah but why don't larger asteroids become round?

the bigger issue IMO is that the only planet according to that definition is, thanks to quasi-satellites and orbital crossings, fucking Mercury lmao

they aren't big enough to attain hydrostatic equilibrium. that's literally it.

isn't a hard boundary though. The bigger the object the more round it becomes.

ye

especially considering that hydrostatic equilibrium isn't exclusive to spheres, they're just the most common. the solar system has a lot of planets in it, and there's nothing fucking wrong with that IAU >:c

Moons aren't planets because they orbit around their planet.
Pluto isnt a planet because it orbits around a fucking random point in space. Pluto is retarded just like /sci/

it's a harder boundary than the IAU definition that it "clears its orbit"

because that means none of these are planets lmfao

here we see the true reasoning behind the IAU decision: they're just pedantic assholes refusing to admit they're wrong by redefining the terms on the fly

also FYI literally all orbits are around barycenters

binary planets break your definition

the Earth/Moon system arguably qualifies as a binary planetary system

Apparently this was an actual alternative considered before
https://en.m.wikipedia.org/wiki/Double_planet
>At its 2006 General Assembly, the International Astronomical Union considered a proposal that Pluto and Charon be reclassified as a double planet,[4] but the proposal was abandoned in favor of the current IAU definition of planet.

Yeah but 99% the time the barycenter is inside the planet.

Nope. They're binary planets.

>the Earth/Moon system arguably qualifies as a binary planetary system
Barycenter inside earth therefore earth is the planet. Moon is a moon.

there are even similar surface differences, with Charon being heavily cratered and Pluto exhibiting significant evidence of literal fucking geology

It axiomatically follows that anyone who subscribes to the notion of infinity is a sodomite. Why else would they believe in infinity? In turn subscribing to the notion of infinity and being cursed by GOD for performing unnatural acts axiomatically disqualifies people from having the right to an opinion. I am sure you will agree its entirely logical and based upon empirical evidence. Unless of course you are a FILTHY INFINITY LOVING SODOMITE, in which case you shall surely burn in the FIRES OF HELL.
Amen.

Nah thanks, lets keep it simple for now, we can deal with needing several levels of classification when we are colonizing things that aren't planets or moons.

Planets have much more meaning culturally than they do scientifically anyways. Who cares as long as you have it’s physical properties correct? If it matters so much, just create some new classification name that includes the first eight planets and nothing else, and use that instead when discussing astrophysics. This classification nonsense is probably the least useful-to-humanity part of astrophysics anyways.

Earth's moon is certainly a planet. But tell me this--would you consider Mars' moons Deimos and Phobos planets?
In any event, if you group the moon with Earth, Uranus etc will you then commit to memory the moons of Jupiter and Saturn, which number in the dozens?
