Lissajousorbit

In the space flight mechanics is the Lissajousorbit, [ li.sa.ʒu ], named after Jules Antoine Lissajous, a quasi-periodic trajectory, which can follow an object by a Lagrangian point of a three-body system without the use of fuel.

Lyapunov orbits around a libration point are curved tracks that are entirely in the plane of the main body; In contrast, Lissajousorbits contain components in this plane and perpendicular to it and follow a Lissajous figure. Halo orbits also include components perpendicular to the plane, but are in contrast to Lissajousorbits periodically.
