Piero Sicoli (born 1954) is an Italian astronomer and discoverer of minor planets, observing at the Italian Sormano Astronomical Observatory. [2] As the observatory's coordinator, he is responsible for close encounters computation of near-Earth objects (NEOs), [3] 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. [4]
The Nysa asteroid 7866 Sicoli, discovered by Edward Bowell at Anderson Mesa Station in 1982, is named in his honor. [2]

(35396) 1997 XF11 (provisional designation 1997 XF11) is a kilometer-sized asteroid, classified as a near-Earth object, Mars-crosser and potentially hazardous asteroid of the Apollo group.
Stefano Sposetti is a Swiss amateur astronomer and a prolific discoverer of minor planets. He lives in Gnosca, in the Italian-speaking part of Switzerland in the Ticino Alps, where the Gnosca Observatory is located.
Francesco Manca is an Italian amateur astronomer and discoverer of minor planets at the Sormano Astronomical Observatory in northern Italy.
Marco Cavagna was an Italian amateur astronomer.
Paolo Chiavenna is an Italian amateur astronomer and a co-discoverer of minor planets, credited by the Minor Planet Center with the discovery of 15 minor planets during 1995–2000.
The Observatory of Turin is an astronomical observatory owned and operated by Italy's National Institute for Astrophysics. It is located on the top of a hill in the town of Pino Torinese near Turin, in the north Italian Piedmont region. The observatory was founded in 1759. At Pino Torinese, several asteroid discoveries were made by Italian astronomer Luigi Volta in the late 1920s and early 1930s. The asteroid 2694 Pino Torinese was named after the observatory's location.
The Pistoia Mountains Astronomical Observatory, also known as the San Marcello Observatory and the Pian dei Termini Observatory, is an astronomical observatory in San Marcello Piteglio, Tuscany, central Italy.
(137108) 1999 AN10 is a kilometer-length near-Earth asteroid and potentially hazardous asteroid of the Apollo group. It was discovered by LINEAR on 13 January 1999.
9115 Battisti, provisional designation 1997 DG, is a stony Vestian asteroid from the inner regions of the asteroid belt, approximately 5.5 kilometers in diameter. It was discovered on 27 February 1997, by Italian astronomers Piero Sicoli and Francesco Manca at Sormano Astronomical Observatory in northern Italy. The asteroid was named for Italian singer-songwriter Lucio Battisti.
15460 Manca, provisional designation 1998 YD10, is a Koronian asteroid from the outer region of the asteroid belt, approximately 5 kilometers in diameter.
7866 Sicoli, provisional designation 1982 TK, is a stony Nysa asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 13 October 1982, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona. The asteroid was named after Italian astronomer Piero Sicoli.
6882 Sormano (prov. designation: 1995 CC1) is an stony Eunomia asteroid from the middle region of the asteroid belt, approximately 7 kilometers (4.3 miles) in diameter. It was discovered on 5 February 1995, by Italian amateur astronomers Piero Sicoli and Valter Giuliani at Sormano Astronomical Observatory in northern Italy. The asteroid was named for the Italian mountain-village of Sormano and its discovering observatory.
A potentially hazardous object (PHO) is a near-Earth object – either an asteroid or a comet – with an orbit that can make close approaches to the Earth and which is large enough to cause significant regional damage in the event of impact. They are conventionally defined as having a minimum orbit intersection distance with Earth of less than 0.05 astronomical units and an absolute magnitude of 22 or brighter, the latter of which roughly corresponds to a size larger than 140 meters. More than 99% of the known potentially hazardous objects are no impact threat over the next 100 years. As of September 2022, just 17 of the known potentially hazardous objects listed on the Sentry Risk Table could not be excluded as potential threats over the next hundred years. Over hundreds if not thousands of years though, the orbits of some "potentially hazardous" asteroids can evolve to live up to their namesake.
(4953) 1990 MU is a large Earth-crossing asteroid (ECA) belonging to the Apollo group of near-Earth objects which also cross the orbits of Mars and Venus. At approximately 3 km in diameter, it is one of the largest known ECAs. It has been assigned a permanent number from the Minor Planet Center (4953) indicating that its orbit has been very well determined. With an observation arc of 45 years, the asteroid's trajectory and uncertainty regions are well known through to the year 2186.
367943 Duende (provisional designation 2012 DA14) is a micro-asteroid and a near-Earth object of the Aten and Atira group, approximately 30 meters (98 ft) in diameter. It was discovered by astronomers of the Astronomical Observatory of Mallorca at its robotic La Sagra Observatory in 2012, and named for the duende, a goblin-like creature from Iberian and Filipino mythology and folklore. Duende is likely an uncommon L-type asteroid and significantly elongated. For an asteroid of its size, it has a relatively long rotation period of 9.485 hours.
The Sormano Astronomical Observatory is an astronomical observatory north of Milan, Italy. Located near the Swiss border at 1000 meters elevation at the mountain village of Sormano in the pre-Alps, the observatory was privately funded by the Gruppo Astrofili Brianza and built in 1986.
2013 GM3 is a micro-asteroid, classified as near-Earth object of the Aten group, approximately 20 meters in diameter. It was first observed on 3 April 2013, by astronomers of the Mount Lemmon Survey conducted at the Mount Lemmon Observatory near Tucson, Arizona, United States.
2017 YE5 is a binary pair of asteroids of approximately equal size and mass, each about 0.9 km (0.56 mi) in diameter. Classified as a near-Earth asteroid and potentially hazardous object of the Apollo group, 2017 YE5 was discovered by amateur astronomer Claudine Rinner at the Oukaïmeden Observatory on 21 December 2017. On 21 June 2018, the pair of asteroids passed within 15.5 lunar distances or approximately 6 million km (3.7 million mi) from Earth. During the close encounter, 2017 YE5 was resolved in high detail by concurrent radar observations by the Arecibo and Green Bank observatories, along with individual observations by the Goldstone Solar System Radar. 2017 YE5 is likely an extinct or dormant comet due to its distant elliptical orbit and dark red surface.
2020 BX12 is a sub-kilometer binary asteroid, classified as a near-Earth asteroid and potentially hazardous object of the Apollo group. It was discovered on 27 January 2020 by the Asteroid Terrestrial-impact Last Alert System survey at the Mauna Loa Observatory during its approach to Earth of 0.02915 AU (4.361 million km; 11.34 LD). Radar observations of the asteroid were carried out by the Arecibo Observatory on 4 February 2020, revealing a natural satellite orbiting 360 m (1,180 ft) from the primary body.
