I have been experimenting since a few days that I got the program from Steam.
Up to now I managed to place 2 planets close together, after experimenting with different distances and masses, so that they would not collide. At the same time I managed to have them both orbiting around the system's sun despite their close distance and difference in masses. Then I placed some rings on each, waited for the system to stabilize and voila:
2 planets sharing the same debris, travelling close but not orbiting one the other. The little hump on the right was unavoidable. The system stabilized that way because of the sun's gravity. But the good part is that it wasnt enough to take for himself any of the ring material.
Could this happen in reality? I am really curious. By the way I am a chemist-analyst so I have no idea of these stuff. Keep it simple as in university physics.
Thanks a lot.
