🧵 How can a planet be only gas?

Anonymous No. 16617772

Shouldn’t the gas fucking leak everywhere? How can it stay “contained” in a sphere? It doesn’t make sense?

Why doesn't the atmosphere leak away from earth?

Here's the thing, it does. Even from the sun.

Ahem well you see, uhh..ummmm yes well, just trust me on this one. The science is conclusive.

The gas is contained by gravity from the planet being massive, and it isn't only gas, it had a solid rocky/metallic core.
Though you sort of raise a good point, whether or not you thought of it- a gas planet has to be massive (compared to Earth) to hold itself together, and we don't find gas planets that are Earth-size or smaller

a tiny tiny bit does every day. it just requires that individual gas molecules get smashed into by some other particle going much faster in order for them to go fast enough to leave us.

Does electro static forces play a role ?

Typically when we speak about the diameter of Earth, we don't include the atmosphere. For the Gas Giants, we do. If they have solid surfaces under the atmosphere, wouldn't it be consistent to use that? Or maybe the liquid layer?

A planet's surface is determined to where its atmospheric pressure is equal to Earth's sea-level atmospheric pressure. For the gas giants, this extends further out than on the terrestrial planets

Why doesn't the gas collapse into a solid due to the pressure?

It's not purely made of gas, it has a very dense heavy core. Actually it's thought that a planet X masses larger than the Earth CANNOT be a rocky planet, because it will accumulate and be able to retain so many lighter elements, it inevitably develops a large and thick atmosphere. (Exceptions may be stuff like a planet very close to its sun, where solar activity could brush off the planet's atmosphere despite its large gravity)

Too little gravity and the gas will indeed leak out. See: Mars

Wonder how much sooner humans would have made it into space if Earth has the mass of Mars instead. Steampunk Vostok.

You can solve the thermodynamics calculations and find that if the earths atmosphere was hydrogen, it would leak away in a few hundred years. Oxygen/nitrogen molecules are heavier, and they take something like 10 billion years to decrease by 10%

It is unlikely that Jupiter, or any other gas giant, is entirely made of gas. The early solar system had too much rocks and metals in it for that to be true. Most likely it has a metalic or liquid metal core.

We lose approximately 95,000 tons of hydrogen to space each year making our planet slightly drier as it ages since hydrogen is a component of water. Although some of that is refreshed by comets and asteroids bringing water it's a net loss. Eventually Earth will become as dry as Mars.
