Custom finder charts for solar system objects
by Dominic Ford
Showing stars down to mag –
Current mouse position
The chart above is based on the
DE405 planetary ephemeris computed by the Jet Propulsion Laboratory (JPL). 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).
The markers along each track are drawn at midnight each day, in your local time –
Cambridge time (EDT).
Star positions and magnitudes were taken from the
Gaia DR1 catalogs.
