[Orekit Users] CelestialBody Position extrapolation

[<simon.spoerri@students.fhnw.ch>]

Dear all,

i'd like to create a discrete sampling of celestial body positions for a
complete orbit of all bodies. I tried both getting positions from the
celestialBody object directly and using a Propagator to get positions of the
orbits. However i run into ephemerides constraints and cannot obtain
coordinates past around 2030 (Error: out of range date for EARTH_MOON
ephemerides: 2030-05-20T14:36:30.712).
I try to obtain the positions in the SolarSystemBarycenter Frame.
My question is if it is possible at all in Orekit to extrapolate body positions
around 150 years into the future/past? I know that this is not the main purpose
of Orekit and I do not require very accurate results, nevertheless i wanted to
use Orekit for that for convenience...
And if it is possible, how should i do it?

thanks a lot in advance,
Simon
