For what definition of stable? Stable in 2d? 3d? 3d + expected disturbances from solar winds, passing objects, solar flares, etc? How about the decreasing mass of the sun? Over a year? Century? Million? Billion?
- astrodust 9y agoThe atmospheric drag on a planet could make its orbit wobble enough to cause a cascade effect through the entire system. As soon as one planet wanders a bit too far out of line it'll smack into others going the opposite direction and the debris will take out all the others inside of a few revolutions. Interesting, but highly risky.
