What definition do you think makes the most sense? IAU definition or geophysical definition?
>>16480868anything 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 kgClass II - Mass ranging from 10^22 kg to 10^24 kgand so on(placeholder names and numbers)
>>16480879>Let's make space more autistic.
Moons aren't planets, they're moons.
>>16481145Uhmm actually some moons (such as the Earth's Moon) are Satellite Planets.
>>16480868They’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.
>>16480868IAU 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
>>16481435Neither is Pluto
>>16480868IMO:::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
>>16480868Was about to reply seriously, when I saw the filename.(You)
>>16481691Explain
>>16482024He doesn't need to explain nuffin
>>16480868Any 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.
