The paths of the planets are taken from the DE430 planetary ephemeris computed by the Jet Propulsion Laboratory (JPL). Planetary positions were extracted from the DE430 files using EphemerisCompute, which was also written by the author, and is also freely available for download.

Asteroid positions are computed from orbital elements made available by Ted Bowell at the Lowell Observatory. Comet positions are computed from orbital elements published by the Minor Planet Center (MPC).

Star positions and magnitudes were taken from the Hipparcos, Tycho, Tycho-2 and Gaia DR1 catalogs.
