Planetary Ephemeris Programs in PHP

These programs provide basic, but very accurate planetary ephemerides (almanacs) based on the NASA/JPL DE405 Ephemeris Model.  They span the 600-year period from 1600 to 2200 and cover the sun, moon, all the planets and Pluto.

The IAU 1980 nutation series and the NASA polynomial approximations for the Delta T (ΔT) estimate resolved to the nearest second are applied to the computations.
