A neutral point is a point in space at which a particle experiences no net gravitational force. In theory, a unique neutral point would exist between any two static bodies. In practice, when two objects, such as Earth and the Moon are orbiting each other, there are five points, known as Lagrangian points, at which gravitational and centrifugal forces are exactly in balance.
