# How wide is the $L_4$ and $L_5$ Moon-Earth Lagrangian point?

How far would an object need to be displaced from the $$L_4$$ and $$L_5$$ Lagrangian points so that it can escape returning to those points?

• Useful paper discussing how the stability of $L_4$ and $L_5$ is due solely to the Coriolis effect: wmap.gsfc.nasa.gov/media/ContentMedia/lagrange.pdf The stability analysis here could be extended to investigate what happens in the vicinity of the points rather than at the points. – G.
