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.

Newtonian gravity also follows an inverse square law, so that moving an object twice as far away divides its gravitational force by four, and moving it ten times as far away divides it by 100. This is similar to the intensity of light, which also follows an inverse square law: with relation to distance, light becomes less visible.
