Position-calculator for the Sun, Moon, Mercury through Neptune (VSOP87d-theory) by Robert von Heeren


 
 
Positions of the Sun, Moon through Neptune are calculated online according to the full VSOP87d-theory (not truncated) and are accurate to one arcsecond.
The full IAU1980-nutation-series, newest DeltaT-values and approximations, light time and FK4-FK5-differences are taken into account.
Years between 2000 B.C. and 6000 A.D. are allowed.
 
If you want to get sophisticated ephemerides and/or astronomical data about Minor Planets use JPL's free Horizon's webinterface.
Allowed time range is shorter than for the VSOP87d-routines here.
Dates between 1601 and 2198 A.D. (in some cases maybe even less time range) are computed by JPL.
