Is it possible to determine the position of orbiting exoplanets after eg. 50 years? Many parameters of the orbits have large estimates eg .: Tau Ceti f: Orbital period (P) = 642 ± 30 days. It is up to ± 30 days (and this is just an example).
Is there a way to calculate quite precisely the position of the exoplanets after 50 years or more? (Starting from today, of course)
What kind of precision you can get? (In most cases, of course)
