anything that closely resembles the radius of your mom's ass.

Planet is a stupid historic label.
We should use a metric system to identify space objects.

Like for example:
Class I - Mass ranging from 10^20 kg to 10^22 kg
Class II - Mass ranging from 10^22 kg to 10^24 kg
and so on

Moons aren't planets, they're moons.

Uhmm actually some moons (such as the Earth's Moon) are Satellite Planets.

They’re all arbitrary in a sense. Take Pluto. Its barycenter with Charon lies outside its radius. And, of course, astrophysicists will cope by saying it’s a “minor planet” or a “dwarf planet”. But it’s not inconceivable to have some anomalous star system with an Earth-sized planet having such a massive moon that their barycenter is outside their Roche limit.

Similarly, dwarf planets have more in common with rocky planets than gas giants. There is the same vagueness in definitions. What is Jupiter’s radius? Fuck if I know because there’s no clear solid boundary. But I can tell you Earth’s or Pluto’s average radius just fine despite them supposedly being in two different classes.

And then there are double and triple star systems where it all goes to hell. Is a rocky object orbiting a brown dwarf orbiting a star a planet or a moon? Really depends on whom you ask.

IAU seems fine. Having enough mass to clear its orbit of objects or capture said objects sounds about right.

the moon isn't a planet faggot, give it up

IMO:::
Big enough to be round and with a rocky surface, it's a planet.
Big enough to be round but without a rocky surface, it's a gas "giant" (or whatever you want to call it; gas planet, gas sphere, gas ass)
Big enough to be round and glowing by way of nuclear furnace, it's a star

Everything else gets to keep the same designations. an asteroid is some shit that isn't big enough to be round (demos and phobos are thus satellite asteroids)
comet is used to clean your sink etc

Any significant enough body of mass capable of unifying it's matter into a sphere like geometric shape, clear out its immediate orbital environment from any major material space debris through absorption and one that orbits not another body of rock or small gas but a star.
That would be a planet.
