It is the minimum potential equilibrium among L₁, L₂, L₃, L₄ and L₅. It is the easiest way for the debris to commute between a Hill sphere (an inner circle of blue and light blue) and communal gravity regions (figure-eights of yellow and green in the inner side).

L₂ and L₃ are gravitational perturbation equilibria points. Passing through these two equilibrium points, debris can commute between the external region (figure-eights
