Li`bra´tion point` (lî`brā´shŭn point`) n. 1. any one of five points in the plane of a system of two large astronomical bodies orbiting each other, as the Earth-moon system, where the gravitational pull of the two bodies on an object are approximately equal, and in opposite directions. A solid object moving in the same velocity and direction as such a libration point will remain in gravitational equilibrium with the two bodies of the system and not fall toward either body

When did they change the name? It used to be LaGrange points.
Do I need to change my screen name?

Nasa is wanting 20 years to design a capsule. It only took them 8 years for the entire moon program. We aren’t going anywhere.

By the way, if I remember my Celestial Mechanics classes, only L4 and L5 are truly “stable”. The others are “meta-stable”, which means that they are stable in two dimensions only. L4 and L5 are stable in three dimensions.
