Do the L4 and L5 points travel in a geodesic?

  1. Jan 7, 2007 #1
    Given a two body system like the sun and the earth:

    Do the L4 and L5 points travel in a geodesic, or is it just the sun and the earth which do so?

    The two body problem in GR is fiendishly complicated and can only be solved numerically.

    However, having said that, test-particles co-orbiting in the L4 or L5 points are in free fall, and in GR they would travel along geodesics.
