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.
