List objects located at a point of Lagrange

Here a list of objects (Astéroïde S, space probes, etc) which occupied, occupy or should occupy one of the five points of Lagrange of a system of two celestial objects.

Ground - Sun

L1

The point of Lagrange L1 is located at approximately 1.500.000 km of the Ground in direction of the Sun.

  • Old probes:

  • current Probes:

    • SoHO
    • Advanced Composition To explore

  • future Probes:

    • LISA Pathfinder

  • cancelled Probes:

    • Triana

L2

The point of Lagrange L2 is located at approximately 1.500.000 km of the Earth in the direction opposed to the Sun.

  • current Probes:

    • Wilkinson Microwave Anisotropy Honest (WMAP)

  • cancelled Probes:

    • Space telescope Eddington

L3

The point of Lagrange L3 is located on the other side of the Sun compared to the Earth, slightly beyond the terrestrial orbit. Currently, one knows no object located at this position.

L4

The point of Lagrange L4 is located on the terrestrial orbit, in advance of 60° compared to the Earth. It seems to shelter clouds of dust.

L5

The point of Lagrange L5 is located on the terrestrial orbit, late of 60° compared to the Earth. It seems to shelter clouds of dust.
