FastFourierTransform:Source of the post I've just saw the precession of Mercury's perihelion. It's beautifull. But the problem is that it uses the DE436 theory that goes from the year 1550 to the year 2560. After that it imediatelly stops. If VSOP87 is also implemented and has unlimited timespan, why we can't see further evolution of Mercury's orbit?
FastFourierTransform:Source of the post Precession of Mercury's perihelion: I saw it in SE and looks great, but only occurs from the year 1550 to the 2560. Considering this is a more or less periodic phenomena could you make the timespan for the precession bigger? In that way we could see further evolution of Mercury's orbit. It's a very small angle now and If one has to explain it to people they are not going to clearly see it if it is not with longer duration.
SpaceEngineer:Source of the post JPL ephemeris does not calculate that value directly, so it cannot be extrapolated above the end points of the simulation.
