Humans in KSP

Yeah, I think it's worse that that, @MaverickSawyer.  At 1/10 the diameter, Kerbin is 1/1000 the volume of Earth.  That would give 1/10 G if it were the same density as Earth (though if it were the same materials, it would be less dense, because even IRON compresses a good bit when there's a whole planet sitting on it).  It would need ten times the mass to get back to 1 G (gravity is linear with mass, inverse square with radius).   Earth is denser than iron, overall, because the iron core is compressed (offsetting the less dense rock of the upper and lower mantle and the still less dense crust), so you'd need something twice as dense as tungsten or gold -- which is a good big denser even than osmium.  IOW, Kerbin and all the other bodies in the system must have cores of (at least) degenerate matter, with the electrons at least partially crushed down into the nuclei. Oddly, the asteroids don't seem to have this; they're about the right size to be made of ordinary rock.
