SUMMARY
The gravitational potential at the neutral point between two masses, such as Earth and the Moon, does not equal zero due to the nature of the gravitational potential function, u(r) = -\left(\frac{GM_e}{|r|} + \frac{GM_m}{|R_m-r|}\right), which is negative definite for all finite values of r. The term "neutral point" can have multiple interpretations, but in this context, it refers to the point where the gravitational forces from both masses are equal. The potential is measured from infinity, meaning it only reaches zero at an infinite distance from both bodies.
