Distances, relative velocity and acceleration between planets

The coefficient tables used by the website are derived from Planetary theories in rectangular and spherical variables-VSOP 87 solutions by Pierre Bretagnon, Pierre, and Gérard Francou and published in Astronomy and Astrophysics, vol. 202, Aug. 1988, p. 309-315. The VSOP87C (Heliocentric ecliptic rectangular coordinates) tables are used.

The original solution tables are available by FTP.
