Orbital Mechanics (Rocket and Space Technology)

Orbital simulations by Varadi, Ghil and Runnegar (2003) provide another, slightly different series for Earth orbit eccentricity, and also a series for orbital inclination. Orbits for the other planets were also calculated, by , but only the eccentricity data for Earth and Mercury are available online.
