Double planet orbits?

[Anima]

I'm working on an add-on for a binary planet system.

I want to know how I would implement the orbiting system below.

Well, you could look at Pluto in the ssc file. It's got the information you need, just tweak the values a bit.

Last I looked, Pluto and Charon had a custom orbit.

The concept is the same:

Define a barycenter (ReferencePoint in SSC files) orbiting the star, perhaps using an EllipticalOrbit.
Define the planets to be orbiting that barycenter.
Their orbits essentially have to be mirror images of one another, so the planets are always on opposite sides of the barycenter.
