A spherical planet far out in space has a mass ${M_0}$ and diameter ${D_0}$. A particle of mass m falling freely near the surface of this planet will experience an acceleration due to gravity which is equal to
$g = \frac{{GM}}{{{R^2}}} = \frac{{G{M_0}}}{{{{({D_0}/2)}^2}}} = \frac{{4G{M_0}}}{{D_0^2}}$
