This is a collection of files in xephem database format. Included here are asteroids, comets, stars, deep-sky objects, earth satellites and spacecraft. Work on the databases is a major project in itself. There are bound to be errors.
Authoritative contributions welcome.
A few with common names have been renamed. Messier.edb is the Messier catalog. Asteroids which can ever be at least mag 13 are in asteroids.edb. They are named with their sequence number followed by their common name, if one has been assigned. Version 6.0 are in SAC.edb.
