Do Pluto and Charon have unusual Langrange points?

The usual examples of Lagrange point mechanics one most commonly encounters, Sun-Earth-L# and Earth-Moon-L#, are examples of 3-body problems where 1 >> 2 >> 3 in terms of their mass. The Pluto-Charon ...

How stable are Lissajous orbits?

Now that the Gaia Space Telescope is on it's way to the Sun-Earth L2 Lagrangian point (SEL2), I start wondering about the stability of Gaia's orbit there. The Planck Telescope is already there, as was ...
