The Asteroid Orbital Elements Database - An ASCII file of high-precision osculating orbital elements, ephemeris uncertainties, and additional data for all numbered asteroids and majority of unnumbered asteroids for which it is possible to make reasonably determinate computations.
Asteroids - Includes student project award, hunting, and grants issued presented by Sky and Telescope.
IAU - Minor Planet Center - Is responsible for the efficient collection, checking, and dissemination of astrometric observations and orbits for minor planets and comets, via the Minor Planet Circulars (issued monthly) and the Minor Planet Electronic Circulars (issued as necessary).
Minor Planet - Dedicated to astronomical imaging and positional data, and includes information on observatories, news, images, star charts, fits data, and shareware.
Small-Body Orbital Elements - Provides access to orbital elements for numbered asteroids, unnumbered asteroids, and comets with element tables using a custom generator (using the current DASTCOM database) or ASCII files.
- A list for asteroid and comet researchers.
