I suppose two Jupiters on the same orbital plane, 180 degrees from each other, would cancel out? Is it possible for observers to really know we have 4 rocky planets, 4 gas giants, and what their mass is, etc? Or, with what degree of certainty could this be known, and from what distance?
- animal531 9y agoI don't believe you can have 2 planets in the same orbit, and once they're in different orbits they'll take a different amount of time to orbit; so you should be able to get individual measurements. Edit: Well, as per the simulated stable thread, apparently you can have Trojan etc pairs of planets in the same orbit. Interesting.
- Already__Taken 9y agoThere's possible and there's likely to happen in nature. two opposing planets in symmetry you'd have to have symmetric mass all around to cancel the forces out. One side will have the galactic centre on and the other won't might even be enough of a tiny imbalance to disrupt the orbits as you say.
