How to Define a Binary Planet?

If you have read the Rocheworld series by Robert L. Forward, you know what this is.

A binary planet is a planet that is actually a double planet which orbits about a barycenter.

Attached are two images exported from Celestia.

I have been looking through the program and the PDF doc, but I cannot find how to add a binary planet.

Thanks for any help.

  • It all depends if you are using Astro 3 or not. This what a binary planet or "planet system" looks like in Astro 3.
