Proper Elements Catalogs

The catalogs contain proper orbital elements of numbered asteroids and main-belt comets computed numerically by means of a synthetic theory by Knežević & Milani (2000,2003).

There are however some differences between the procedure proposed by aforementioned authors and the one used to produce the catalogs available here:

Asteroid proper orbital elements (available for 793,310 objects in total, as of January 2021):

Numbered asteroids (507449 objects):

Multi-opposition asteroids (123777 objects):

Proper orbital elements for active main-belt asteroids:
