... and are therefore no longer satellites. https://www.nasa.gov/audience/forstudents/5-8/features/nasa-... https://www.nasa.gov/audience/forstudents/5-8/features/nasa-...

Some Lagrange points are stable and therefore will not decay toward the Earth outside of other factors. (Because these systems are never sufficiently isolated, in the eternal view, therefore, also still require energy, though much, much less.) Though, of course, an object at a Lagrange point may still not technically be a satellite of earth. https://solarsystem.nasa.gov/faq/88/what-are-lagrange-points (though by the NASA definition above I'd argue that they are)

Lagrange points L1,2,3 are metastable and all are also perturbed by all the reality of not being result of two point masses in perfect vacuum.
