  •  Gravity on most super-Earths, as far as I've seen (1+ / 0-)

    wouldn't be that much higher than on Earth.  Having twice the mass of Earth doesn't mean twice the gravity.  Density as a product of composition determines surface gravity.  If it's mostly silicate with a smaller iron core, the gravity won't go up at much of a rate with greater mass.

    Pour yourself into the future.
