Sorry about the bad stat on Jupiter's mass in solar masses. What you do need to realize is Jupiter isn't exactly stable. Remember it's eye & ponder on that convolution. Then it radically started to change, even in respect to its location to the meridian. I'm not an expert on this as you have all seen, but the power behind this & the coriolis force involved is a classic for any planetary techtonic who wants to find a case study. We are fortunate to have such a presence within the Solar system to study by & learn from.
