Kepler is a library of C routines for astronomical calculations. It features the following:

  • The entire VSOP87 theory for calculating the positions of the eight planets.
  • The entire ELP 2000-82B theory for calculating the position of the Moon.
  • An analytical theory for calculating Pluto's position for the period 1700AD-2100AD.
  • The ability to convert osculating orbital elements to heliocentric coordinates.
  • The latest IAU 2006 precession and IAU 2000A nutation models.
  • Routines for calculating sidereal time using the current IAU resolutions.
  • An implementation of the Ron/Vondrak theory of annual aberration.
  • Routines for Julian date calculations.
  • Routines for coordinate transformations, rotations and parallax corrections.
