minus-squarecogitase@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up0·8 days agoIs there a lower density limit for having a magnetosphere though? A habitable planet with 1.5x earth radius and the same mass would be much easier to get off of.
minus-squareCheeseNoodle@lemmy.worldlinkfedilinkEnglisharrow-up0·8 days agoI guess that could work? Earth is actually the densest planet in the solar system so our baseline mass > size ratio might actually be a bit abnormal.
minus-squareMrFinnbean@lemmy.worldlinkfedilinkEnglisharrow-up0·7 days agoI was sure you were bullshitting, but no. Its true. Iron and nickel core + enough mass for gravity to start compress the planed and we are just little more dense than Mercury.
