Catalog of orbits for all numbered asteroids; they are provided in the OEF format, computer readable by means of the OrbFit free software

Numbered asteroids

Multiopposition asteroids

Single opposition asteroids

The catalogs below contain orbits of single oppostion asteroids, observed over at least 3 separate nights. Note that the orbits have been fitted to the observational data made available by the MPC at the last complete update. If an asteroid has been reobserved in the meantime, the orbit given here is not up to date.

The objects included in the catalogs below are not included in the AstDyS online system, that is they do not have an individual object home page. If you need ephemerides, you can compute them by using the OrbFit free software.
