Would it be correct to assume that over a period of time, possibly millions of years, that pulto would also join the orbial plane that the other planets occupy?
I'm thinking that a comet, foreign to our solar system, has inertia and is following a vector that is different to our orbital plane. If said commet has sufficient inertia to escape our Sun's gravitiational pull it can only be bent in another direction and leave our solar system. If the comet's inertia is insufficent, it could be trapped in our solar system. It's path would be determined by it's inertia, vector and influenced by the gravity inside our solar system, eventually it's inertia will decay and it will find itself orbiting amoung the same plane as the other planets.
Am I correct in these assumptions?
Thanks guys/gals, you provie a great deal of insight.
