About Mercury
The position above was computed with the VSOP87D theory (Bretagnon & Francou 1988), the standard analytical theory of IMCCE/Bureau des Longitudes. Values are apparent geocentric, with iterative light-time correction (3 passes), ecliptic-to-equator conversion via mean obliquity (Meeus Eq. 22.2), and freely available through open source.
Typical precision: 1-3 arcsec in RA/Dec for the 1900-2100 window, with controlled degradation up to ~arc-min at the 4000 BC and 3000 AD extremes. For maximum precision, use JPL Horizons. See the precision page for numerical validation.
