Orbital Data

These data sets contain derived data relating to the orbits of objects.
These data sets will include the proper elements and dynamical families. Orbital observations can be ground based or from spacecraft. Orbital data sets are typically collected over a longer time period to allow for a complete observation of an orbital path.

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:
