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. WebFeb 3, 2024 · The gravity field of a body is a mathematical description and estimate of the complex gravity potential of that body. Depending on the accuracy with which the gravity was measured, there could be thousands of terms to the model, which is typically described in terms of spherical harmonic coefficients.
