On the tab that opens on the bottom left after the star is selected, where it reads 'Still, Orbit, Binary & Launch,' select 'Binary.'.

Place the first star anywhere in the simulation.

I like to use 'Add > Random Main Sequence Star' to select it.

Therefore, only this method of categorising the binaries, which is closely related to the way the planets are arranged about the stars, will be discussed. While it is true that there are alternate methods of classifying binary systems, if you intend to design a custom star system, it really wouldn't be complete without a planet or two. These two configurations are dependent on whether a planet exists or not. If a planet-or planets-isn't there, there would be no P-type or S-type orbits. It should be noted that P-type and S-type orbits really describes the orbit of the planet in relation to the stars. The image to the right displays an example of how this can be possible. This is the P-type portion of the system. This planet orbits the barycenter of the two stars, and because of its large distance, its orbit is not affected by the two stars orbiting each other to a significant degree. Then, at a very far distance away from both stars lies the second planet.

This is the S-type portion of the system. Because of how close it is to one of the stars, the gravitational pull of the star is strong enough to keep it in its orbit and not let it be influenced by the gravitational pull of the other star in the system. Around one of the stars exists a planet with a very short orbital period of several days. Imagine a system where the two binaries are separated by a medium distance. Hydrid Systems A hybrid of a P-type and S-type orbit is possible.
