I am taking an introductory astronomy course and am having problems finding the calculations needed for this problem. It is not a homework problem, just an extra question at the end of a chapter. I have asked my professor about this, and he is not sure either...any help is greatly appreciated. I know the answer is approx 11.9 years, I have no reference in either textbooks I have consulted. It is a "trial by error" problem, but I don't have a clue where to start.(adsbygoogle = window.adsbygoogle || []).push({});

Question:

The synodic period of Jupiter is 399 days.* What is the interval of time between successive times that Jupiter appears in opposition at the same position among the stars?* (this is a trial by error problem)
