Piero Sicoli (b. 1954) is an Italian astronomer and discoverer of minor planets, observing at the Italian Sormano Astronomical Observatory. As the observatory's coordinator, he is responsible for close encounters computation of near-Earth objects (NEOs), orbit computations, and identification of asteroids (about one thousand, included 17 NEOs). The Observatory's focus is the examination and tracking of NEOs in Solar System.
The Nysa asteroid 7866 Sicoli, discovered by Edward Bowell at Anderson Mesa Station in 1982, is named in his honor.
