Gran Sasso of Italy

The CINEOS program (Campo Imperatore Near-Earth Object Survey), started in 2001, is dedicated to the discovery and follow-up of near-Earth objects (NEOs), namely asteroids and comets which periodically approach or intersect the Earth's orbit. In particular CINEOS is addressed to the discovery of Atens and Interior-Earth Objects (IEOs) by extending survey coverage at small solar elongations, and to the discovery of the other kind of NEOs by observing with longer exposures (up to a limiting magnitude of 21) in the opposition region.
