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 ... WebApproach of Earth Gravity Field and Geoid PAGravf4.5 PPT WebFrom the gravity standpoint, sure. Surface gravity is proportional to M/r^2, so you want planet mass M to be double as well. Area is proportional to r 2, so 2 x the surface area means sqrt(2) x the radius, which means 2^(3/2) or 2.82 times the volume.. That means the average density = M/V is 2/2^(3/2) = 1/sqrt(2) = 0.707 times that of Earth. flint is which type of rock
