NEODyS

NEODyS (Near Earth Objects Dynamic Site) is a Italian-based service that tracks all near-earth asteroids, including calculation of orbital elements and impact threat assessment. Together with NASA JPL's Near-Earth Object Program, it is one of the two main sources of information about near-earth objects.
