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.
