thumb|For four years beginning in May 2010, the Pan-STARRS observatory surveyed the entire three-quarters of the sky visible from Hawaii many times in many colors of light. One of the survey's goals was to look for moving objects and transient or variable objects, including asteroids that could potentially threaten the Earth.

NEODyS (Near Earth Objects Dynamic Site) is an Italian service that provides information on near-Earth objects with a Web-based interface. It is based on a continually and (almost) automatically maintained database of near earth asteroid orbits. This site provides a number of services to the NEO community. The main service is an impact monitoring system (CLOMON2) of all near-Earth asteroids covering a period until the year 2100.

orbit@home was a BOINC-based volunteer computing project of the Planetary Science Institute. It uses the "Orbit Reconstruction, Simulation and Analysis" framework to optimize the search strategies that are used to find near-Earth objects.
