Oh, I get why Jupiter our biggest planet is not here. Because its surface is made from gas, not land

[–] EntropyFlux@lemmy.world 2 points 2 days ago

It took me a split second but Jupiter and Saturn are gas giants with really no solid core. It always blows my mind.

Doesn’t Jupiter have a diamond core lol

I guess after searching, that is why we sent Juno to Jupiter?

Damm Earth is big

[–] ksigley@lemmy.world 6 points 5 days ago

There really is an xkcd for everything.

TIL Ganymede is bigger than Mercury?

[–] UnderpantsWeevil@lemmy.world 5 points 6 days ago (2 children)

Hard to say with the irregular shape, but they're close.

What really gets me is how small Mars is relative to Earth and Venus.

[–] nailbar@sopuli.xyz 1 points 4 days ago

The picture got me curious, so I went to check on Wikipedia. It's just bonkers that moons are bigger than planets.

[–] squaresinger@lemmy.world 2 points 6 days ago (2 children)

Kinda shows how useless the fantasy of living on Mars really is. Not only is this a barren wasteland, it's also a tiny barren wasteland.

I/3 the gravity as well, so watch out for that bone density

Why does this look like bootleg Tamriel sans the high elf island I can't remember the name of fuck off Sheogorath it is not the Shivering Isles.

Isnt Jupiter mostly gas/liquid with only a solid core?

[–] Blackmist@feddit.uk 11 points 6 days ago (1 children)

Does it even have a solid core?

[–] gandalf_der_12te@discuss.tchncs.de 10 points 6 days ago (1 children)

probably? according to this diagram, it consists mostly of metallic hydrogen, which i interpret to mean "hydrogen in a solid phase".

[–] Blackmist@feddit.uk 10 points 6 days ago (1 children)

Metallic Hydrogen apparently just means "hydrogen in a state that conducts electricity". No idea what kind of pressure and temperate would form actually solid hydrogen, but from my understanding the gas giants are quite hot internally.

And by that diagram the core would be massive.

From what I can see it's a diffuse core, meaning it's a gas until it isn't, but with no real line between the two.

yeah i read up on it and all four giants (jupiter, saturn, uranus, neptune) have no "clear" surface: they all have a gaseous atmosphere on the surface, but when you go down, it goes above the critical point and therefore continuously changes into a liquid phase with no clear line in between. very deep inside, they all have cores made from rocks, but it's rather small compared to the total size of the planet.
