Did Jupiter Go Back to Where It Was Before?

iReporter: I can totally understand how jupiter feels. It started out at three and a half a u, came in probably about one and a half and now it's comfortably out around five point two a u. We're talking like 500 mil years after the start of the solar system. If you did it, like, i time lapse over like, hundreds of millions of years, it would seem pretty chaotic. But maybe there's some other crazy part of this story that we haven't even thought of yet.
