I know that escape velocity is given by v^2 = 2GM/r(adsbygoogle = window.adsbygoogle || []).push({});

My question is what is theapproximateescape speed needed to completely escape the moon & earth's gravity.

Is it the sum of their individual Escape velocities? or is it one equation, with the radius' added and masses added?

Thanks
