An on-line data-base of Physical properties NEOs, with the corresponding bibliographical references is available for each individual NEA. This data-base, compiled and maintained at DLR by Gerhard Hahn, contains information on all known near-Earth objects (Atens-Apollo-Amor Asteroids), and is updated on a regular basis. It is also linked to, and reachable from the NEO Dynamics Site NEODyS at the University of Pisa, which provides extensive information on all dynamical aspects of NEAs, including close approach predictions and collision probabilities.
The database can be accessed through the European Asteroid Research Node (E.A.R.N) website. Follow the link on the right menu bar.
