| May 7, 2017 at 14:20 | comment | added | David Hammen | Another way to get that factor of $\frac 1 5 f$ is to use spherical harmonics which results in $g = \frac{GM}{r^2}\left(1-\frac 3 2 J_2\frac{a^2}{r^2}(3\cos^2\theta-1)\right) + O(r^{-6}$ , where $J_2$ is the second dynamic form. The factor of $\frac 1 5$ arises from the value of $J_2$ for a uniform density oblate spheroid, $J_2 = \frac 1 5 (1-b^2/a^2)$. | |
