|Asteroid Ephemeris Programs in PHP|
These programs provide basic, but very accurate asteroid ephemerides (almanacs) based on the U.S. Naval Observatory Asteroid Ephemeris - 1998. They span the 299-year period from 1800 to 2099 and cover 15 of the major asteroids.
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.
