The chart above is based on the
DE430 planetary ephemeris computed by the Jet Propulsion Laboratory (JPL).
The positions of asteroids are calculated from
published by Ted Bowell of the Lowell Observatory.
Comet positions are computed from orbital elements published by the
Minor Planet Center (MPC).
The markers along each track are drawn at midnight each day, in your local time –
Fairfield time (EST).
Star positions and magnitudes were taken from the
Gaia EDR3 catalogs.
