Stefano Sposetti (born December 22, 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 Osservatorio Astronomico di Gnosca (Gnosca Observatory) is located.

Sposetti took images of the Aten asteroid 2004 FH which made a close (closer than the moon) flyby of planet Earth.^[4] In addition, he detects the optical counterparts of gamma-ray bursts and conducts transit photometry on exoplanets at his observatory.^[5]

As of September 1, 2015, Sposetti's discoveries include 157 numbered minor plantes. The IAU's Minor Planet Center ranks him 70th in the list of all-time, worldwide discoverers.^[6] The main-belt asteroid 22354 Sposetti has been named after him.^[7]

Flyby of Asteroid 2004 FH in March 2004. The other object that flashes by is an artificial satellite. Images were by Stefano Sposetti and composite by Raoul Behrend of the Geneva Observatory.^[4]
