... by g = GM/R2 for a body of mass M and radius R. By what factor is the gravity on the surface of a white dwarf greater than that on the Earth, if the two have the same radius? The equation gives R = 1R⊕ for a mass of 0.89808 M⊙ – 0.9 M⊙ is close enough. Since the radius is R⊕ for both the Earth and t ...
