ok, so i made a planet orbiting a sun. but i wan't a moon orbit the planet, but when i put ''make banary orbit''
the moon starts orbit the planet, but the path of the planet is going to the sun. so i want the planet orbit the sun, and the moon orbit the planet without sending the planet to the sun.

Orbit parent, orbit all messes up purposful elliptical orbits.

True.

I think binary orbits mean only two objects. So it can't make three objects orbit... using it.

Ahh... I re-read your question and I think I understand the problem now.

If you set two planets to have a binary orbit of one another, they're not given the necessary velocity to orbit the star.

Try this in a simulation with two planets very near each other and a star:

1 - Pause the simulation.
2 - Select just the two planets.
3 - Click on binary orbit
4 - Click on create barycenter.
5 - Now just select the barycenter and the star.
6 - Click on binary orbit

Let me know if that works for you.
No, this works!
