Definition

Two libration points forming equilateral triangles with the two primaries, denoted L₄ and L₅. They are linearly stable when the mass ratio of the two bodies satisfies certain conditions.

Application Value

Triangular Libration Points plays an important role in orbital dynamics and attitude control, serving as a critical tool for analyzing spacecraft motion characteristics. Research on this concept enables optimization of orbit transfer schemes and improvement of control system performance.
