pluto is cool and all but i'm waiting for planet x. that one is going to be the discovery of the century.

not sure if making a joke or if you thought i really meant 10.

and on that topic, i find the need to "clear the neighborhood" to be a bullshit criteria. it essentially puts a proximity limit on planetary classification. if earth was as far out as pluto, earth wouldn't be a planet either, which is stupid.

I wouldn't doubt every single planet has an inner core like ours, just not as large or in a place where it could ever grow.


Just depends. Earth and Venus and Mercury have molten cores. Mars doesn't. Trouble with Pluto is its not very dense. Eris, which is quite a bit smaller, is actually far more massive than Pluto. Up to half of its mass is made up of water ice. There could be a small metallic core, but even if there was a lot of radioactivity going on, the best we could hope for is liquid water slurry surrounding that core. There was talk a few years back that this liquid water, if its there, could harbor life somehow. If there was a spinning core, I'm sure they'd have picked up an EM field with their instruments. Haven't heard anything about that.

Big Bang was way earlier than the planets forming. Solar system is around 5 billion years old. Big Bang was more like 14 billion. Pluto probably formed in the deep freeze, soaking up lighter elements as opposed to heavy rocky stuff because its so far out where the solar wind is weaker. In terms of composition its not much different than all the other Kuiper belt rocks floating around out there. Eris, for example. Though, as I said. Its denser.

Been over a decade for me since comparative planetology. I'm sure a lot has changed.


Yeah, I don't think it would take an actual molten core, just a core that seems molten in comparison to the surface. In a ball of earth ice, seventy degree water in the middle will cause a whole lot of action. Space ice is a hell of a lot colder.

The question of course becomes (assuming there is some amount of heat in the core and that there isn't some other mechanism in play that is entirely possible), why does Pluto have something unique going on inside over the other Kuiper Belt objects? If they formed together, they should be alike. If Pluto is different, it becomes more likely to have either shifted from somewhere else after formation or possibly have collided with something from somewhere else. The trouble is, that "somewhere else" is usually the Kuiper Belt or the Oort Cloud (which just holds even more icy crap).

If I had to guess, I'd bet there is something more going on between Pluto, Charon, and their moons which just make Pluto seem different than other Kuiper objects.

We have a planet 10 honestly, Pluto and Charon should both be planets, even if dwarf.

But on the other hand, Nibiru is coming and you'll be dead soon, so who cares?

charon is a moon so no.

there's some really interesting anomalies going on, at the moment, show objects waaaaay past pluto being influenced by something that appears to be gravity. the only thing that could be doing that is a planetary body or a mass relay.

Charon and Pluto are more realistically binary dwarf planets. They orbit each other.

As for the unexplained gravity, that's God's pad. It generates some serious gravity. The roads are paved in gold, the atmosphere is pure bling, and it has a core of molten bitches.

yes its a joke and yes, i tend to agree. still, we can't call everything that orbits the sun a "planet". but if its basically spherical instead of weirdly shaped... yeah. im fine with that being a planet

while it is true the center of where the two orbit each other is outside of pluto, slightly, unlike earth-moon where the center of orbiting each other is inside of the earth, the center of orbit between jupiter and the sun is outside of the sun

orbiting a barycenter doesn't make something a binary system. they orbit a common point, yes, but pluto's slight wobble isn't anything like charon's actual orbit. otherwise, because the barycenter of the sun and jupiter is outside of the sun, it would make us a binary star system hybrid.

but i'm sure the IAU will make a stupid ass definition that defies logic for that case as well.
