Question

Explain why the outer planets did not lose the lighter gases in their atmospheres.

Answer 1

And I know this is the wrong subject

Answer 2

Well, astrophysics is not my strong point but it's obviously something with the distance from the sun, which would mean either the temperature has something to do with it (less movement of the gasses).

Or maybe it's because of less solar wind or radiation or whatever that would otherwise drive the atmosphere away.

Answer 3

they're much bigger than the inner planets, mainly because they hoovered up a lot of stuff that was very far away from the sun when the solar system formed and the sun was hoovering up all it could in our part of the solar system.

but also because a lot of stuff that was gaseous around the sun would have been frozen by the time it was out there, thus denser. so their solid cores are made of metals like in the inner zone but also frozen hydrogen compounds that were "light" to the sun.

that extra gravity allows them to have dragged in a lot of lighter gas too.
