Definition

The three libration points L1, L2, L3 located on the line joining the two primaries, where centrifugal force and gravity are precisely balanced.

Application Value

The Collinear Libration Point plays a significant role in cislunar space mission design, analysis, and control. In orbital design, it can be leveraged for transfer trajectory optimization; in navigation and control, it improves mission execution precision and reliability; in system analysis, it facilitates deeper understanding of complex multi-body dynamical behavior, guiding mission planning and risk assessment.
