Has anyone tried to model all the Lagrange points of a planet ?
Is is possible to have accurate orbits definition of them in a ssc file ?
It is quite easy with the elliptic orbits, but is it possible with custom orbits ? Any idea Grant for the Earth Sun system, or Earth Moon system ?
Thanks

The moon would be difficult, since its orbit changes over a relatively short time period. I did once have the notion of placing objects at the Earth/Moon L4 and L5 by creating dummy "Earths" inside the real Earth, with their EquatorAscendingNodes set to 60 and -60. Place objects in orbit around these with CustomOrbit "moon", and they'll be displaced 60 degrees either side of the real Moon.

For planet/Sun Lagrange points, the CustomOrbits don't evolve very quickly, and you can produce acceptable results over many years using the plain elliptical elements - just variations on what I've done with the Mars mirrors and the Venus parasol on other threads.
