WebSo: Could a planet with a similar habitable surface to earth but with double the surface area, the same magnetic field and the same gravity exist, and would having it have habitable hollow spaces within the mantle and or a larger thicker crust be possible and be a helpful way of achieving less mass making it possible for earth like gravity to … WebThe main worry would be to reconcile twice the surface with the same gravity. Twice the surface means sqrt(2) times the radius, which in turns means about 2*sqrt(2) times the volume. So we are looking at a planet with a volume of 2.8 times that of Earth. The problem is that such a planet would really need a low density to not have a higher gravity.
