Uncertainty of planetary orbital period

  1. Feb 19, 2012 #1
    I've been searching all over the place, and I cannot find any data showing the error bars of orbital periods of planets. Once source estimates the uncertainty of Jupiter to be "1 arcsec per 250 years" but I cannot find anything to back this up.

    Does anybody have any hints as to where I should be looking?

    Jack, this is a great question, I have been wondering exactly the same thing. I see no one here replied, but did you find this data somewhere else?
