PDS does not maintain an archive of asteroid orbital elements, as
these are calculated on short time-scales. For access to current
asteroid orbital elements on the web, see these sites:
Dr. E. Bowell
at Lowell Observatory maintains a file containing elements for all
numbered asteroids, which he makes available free of charge through his
Web page.
The Minor Planet Center catalogs asteroid and comet identifications
and orbital elements and prepares ephemerides. They are supported by the
user fees they charge for their various services, so there may be a fee
required before they can fill any given request.
