Lagrangian Point
- ColinWright 12y agoWhat is not commonly known is that just as we can do a "gravitational assist" or "slingshot" around a planet, we can also perform a gravitational assist off a Lagrangian point. Specifically, we can "bounce" off L4 or L5 as if it were a body of negative mass. Not sure it's ever been done, though, but the theory is sound.
