Provides additional classes for ephemerides of planets, comets, and asteroids.
This package contains planetary theories different from VSOP87A/D, SERIES96, and ELP2000.
Moshier theory is a fit to JPL DE404 ephemeris. There are also different JPL ephemeris
versions available. Newcomb is an implementation of Newcomb's old solar theory. OrbitEphem
implements also the original VSOP87 solution using orbital elements, and allows the
computation of ephemerides for minor bodies.
