Definition

Regions near the Earth-Moon triangular libration points (L4, L5) where spacecraft can remain for extended periods. Although linear stability analysis shows triangular libration points are center-type stable, nonlinear effects create bounded stability regions where spacecraft can remain for decades.

Application Value

Practical Stability Region plays an important role in orbit maneuver design, analysis, and transfer planning for cislunar missions.
