Gravitational parameter

$\mu =GM=c^2\frac{l_p^2}{{\overline{\lambda }}_M}$

$\mu =c^3\overline{M}=c^2\frac{l_p^2}{{\overline{\lambda }}_M}$

Two body problem

$\mu =G\left(M_1+M_2\right)=c^2\frac{l_p^2}{{\overline{\lambda }}_1}+c^2\frac{l_p^2}{{\overline{\lambda }}_1}$

$c^3\left({\overline{M}}_1+{\overline{M}}_2\right)=c^2\frac{l_p^2}{{\overline{\lambda }}_1}+c^2\frac{l_p^2}{{\overline{\lambda }}_2}$
