The reason for the stability is a second-order effect: as a body moves away from the exact Lagrange position, Coriolis acceleration (which depends on the velocity of an orbiting object and cannot be modeled as a contour map) [22] curves the trajectory into a path around (rather than away from) the point.
Lagrangian point missions Mission Lagrangian point Agency Description International Sun–Earth Explorer 3 (ISEE-3) Sun–Earth L 1: NASA: Launched in 1978, it was the first spacecraft to be put into orbit around a libration point, where it operated for four years in a halo orbit about the L 1 Sun–Earth point.
The orbits for two of the points, L 4 and L 5, are stable, but the halo orbits for L 1 through L 3 are stable only on the order of months. In addition to orbits around Lagrange points, the rich dynamics that arise from the gravitational pull of more than one mass yield interesting trajectories, also known as low energy transfers. [4]

It clearly shows the 5-lagrange points.
The Kordylewski clouds are located near the L 4 and L 5 Lagrange points of the Earth–Moon system. They are about 6 degrees in angular diameter. [7] The clouds can drift up to 6 to 10 degrees from those points. [11] Other observations suggest they move around the Lagrange points in ellipses of about 6 by 2 degrees. [7]

Lagrange point colonization is a proposed form of space colonization [1] of the five equilibrium points in the orbit of a planet or its primary moon, called Lagrange points. The Lagrange points L 4 and L 5 are stable if the mass of the larger body is at least 25 times the mass of the secondary body. [2] [3] Thus, the points L 4 and L 5 in the ...
