Reply to comment by Supermop2000 in If someone were to hypothetically put a sun next to ours as a binary system, would this increase the length of the habitable zone radius of the system? by Country_Royal

Just a question, how does one get a magnetosphere?

Your gonna have to eat a shit load of iron and nickel and spin really fast.

"Not too fast though, and you gotta be real hot. Not too hot though, and you gotta have layers, like an onion. Not sure if you can have too many layers, but you don't wanna be an onion anyway."

So what your saying is that it’s possible.

Possible when we can harvest galactic Amounts of resources and the notion of Terraforming is less fiction.

please don’t try to get yourself a personal magnetosphere. It’s not worth it.

Jokes aside, I believe we’re not really sure how and why intrinsic magnetospheres show up on Earth and Mercury but not Venus and Mars (which have induced ones which block solar wind better instead). Mercury, Earth, and Mars are all known to have liquid core, but it seems Mars’ core isn’t convecting and thus no dynamo.

My understanding is that the problem for Mars and Mercury was that they aren't massive enough to keep their cores hot, so as the cores cooled their planetary dynamos slowed and the magnetospheres dissipated.

Mercury is known to have a magnetosphere (albeit a weak one). by the way.

I don’t have much to say but I like your comment. I didn’t know Mercury has, maybe in some part, a liquid core. Been writing some stuff about Mercury as usual. I found it fascinating in a sense for storytelling wise, a leftover planet. Anyways writing is a whole other tangent lol. Mercury mining while being landlocked by Venus due to technology not advanced enough to drive past planets. I need more world building lol.

It's a little funny to hear Mercury mining now that I know it's weirdly iron-poor on the surface. Despite having the highest core fraction, its surface is really lacking in that stuff. I wonder what resources can be found on the Mercurian surface - I recall carbon is one, but not sure about other stuff aside from the usual silicates.

The dynamo effect. Theoretically if you take a bunch of metallic elements and make them really hot and spinny you get a big ole magnetic field.

Take a planet with a molten center and smash another planet, preferably with water on it into it.. as the internet has led me to believe..
