Stefano Sposetti (born 22 December 1958) is a Swiss amateur astronomer and a prolific discoverer of minor planets.[2][3] He lives in Gnosca, in the Italian-speaking part of Switzerland in the Ticino Alps, where the Gnosca Observatory is located.

Sposetti took images of 2004 FH, an Aten asteroid that made a sub-lunar flyby of Earth.[1] In addition, he detects the optical counterparts of gamma-ray bursts and conducts transit photometry on exoplanets at his observatory.[4]

As of 2019, Sposetti's discoveries include 164 minor planets (numbered only). The Minor Planet Center ranks him 70th in the list of all-time, worldwide discoverers.[5] Asteroid 22354 Sposetti has been named after him.[6]
