The gravitational potential $\phi$ outside a spherical mass distribution of mass $M$ at a distance $r= \sqrt{\left(x^1\right)^2+\left(x^2\right)^2+\left(x^3\right)^2}$ from its center is given by:

$$ \phi(x)=-\frac{G M}{r}

$$

which is the standard formula for the Newtonian Gravitational Potential outside of a spherically symmetric mass distribution (like a star or planet).
