  2. Lagrange point - Wikipedia

    en.wikipedia.org/wiki/Lagrange_point

    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.

  4. Halo orbit - Wikipedia

    en.wikipedia.org/wiki/Halo_orbit

    A halo orbit is a periodic, three-dimensional orbit associated with one of the L 1, L 2 or L 3 Lagrange points in the three-body problem of orbital mechanics.Although a Lagrange point is just a point in empty space, its peculiar characteristic is that it can be orbited by a Lissajous orbit or by a halo orbit.

    Earth-Moon Lagrangian points: a spacecraft in an NRHO around the L2 Lagrange point would have a view of Earth unobstructed by the Moon. A halo orbit is a periodic, three-dimensional orbit associated with one of the L 1, L 2 and L 3 Lagrange points. Near-rectilinear means that some segments of the orbit have a greater curvature than those of an ...

    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]

  8. Jupiter trojan - Wikipedia

    en.wikipedia.org/wiki/Jupiter_trojan

    The trapped body will librate slowly around the point of equilibrium in a tadpole or horseshoe orbit. [10] These leading and trailing points are called the L 4 and L 5 Lagrange points. [11] [Note 1] The first asteroids trapped in Lagrange points were observed more than a century after Lagrange's hypothesis. Those associated with Jupiter were ...

  9. Lagrange point colonization - Wikipedia

    en.wikipedia.org/wiki/Lagrange_point_colonization

    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 ...
