Piero Sicoli 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. The Observatory's focus is the examination and tracking of NEOs in Solar System.
Mount Lemmon Survey (MLS) is a part of the Catalina Sky Survey with observatory code G96. MLS uses a 1.52 m (60 in) cassegrain reflector telescope operated by the Steward Observatory at Mount Lemmon Observatory, which is located at 2,791 meters (9,157 ft) in the Santa Catalina Mountains northeast of Tucson, Arizona.

A formal minor-planet designation is, in its final form, a number–name combination given to a minor planet. Such designation always features a leading number assigned to a body once its orbital path is sufficiently secured. The formal designation is based on the minor planet's provisional designation, which was previously assigned automatically when it had been observed for the first time. Later on, the provisional part of the formal designation may be replaced with a name. Both formal and provisional designations are overseen by the Minor Planet Center (MPC), a branch of the International Astronomical Union.
2253 Espinette, provisional designation 1932 PB, is a stony asteroid and sizable Mars-crosser from the innermost regions of the asteroid belt, approximately 7 kilometers in diameter. Discovered by George Van Biesbroeck in 1932, the asteroid was named after the discoverer's residence "Espinette".
7675 Gorizia, provisional designation 1995 WT5, is a background asteroid from the inner regions of the asteroid belt, approximately 3 kilometers in diameter. It was discovered on 23 November 1995, by the staff at Farra d'Isonzo Observatory in northeastern Italy. It is named for the Italian town of Gorizia.
30705 Idaios is a Jupiter trojan from the Trojan camp, approximately 45 kilometers in diameter. It was discovered during the third Palomar–Leiden Trojan survey at the Palomar Observatory in California in 1977. The dark D-type asteroid has a rotation period of 15.7 hours. It was named after the Trojan herald Idaios from Greek mythology.
4708 Polydoros is a Jupiter trojan from the Trojan camp, approximately 55 kilometers in diameter. It was discovered on 11 September 1988, by American astronomer Carolyn Shoemaker at the Palomar Observatory in California. The D-type asteroid belongs to the 80 largest Jupiter trojans and has a rotation period of 7.5 hours. It was named after the Trojan prince Polydorus, from Greek mythology.
Erwin Schwab is a German amateur astronomer and discoverer of minor planets, who works at the GSI Helmholtz Centre for Heavy Ion Research, near Darmstadt, Germany. He has discovered and co-discovered more than 80 asteroids from the Starkenburg, Tzec Maun and Taunus observatories. As volunteer scientist for the European Space Agency (ESA) he recovered near-Earth objects and comets. From 2014 to 2021 he recovered 30 lost comets, which equates to about 25% of the worldwide proportion in that timespan. Using the Schmidt telescope at Calar Alto Observatory to search for a lost comet he discovered in 2019 a unique variable star – the first known eclipsing stream-fed intermediate polar, cataloged as J1832.4-1627
Kenzo Suzuki is a Japanese astronomer from Toyota, Aichi, Japan. Between 1984 and 1992, he has discovered 42 minor planets mostly in collaboration with astronomers Takeshi Urata and Toshimasa Furuta.
274301 Wikipedia, provisional designation 2008 QH24, is a Vestian asteroid orbiting in the inner region of the asteroid belt, approximately 1 kilometer (0.6 mi) in diameter. It was discovered on 25 August 2008 by astronomers at the Andrushivka Astronomical Observatory in northern Ukraine. The asteroid was named after the online encyclopedia Wikipedia in January 2013.
The Sormano Astronomical Observatory is an astronomical observatory north of Milan, Italy. Located near the Swiss border at 1000 meters altitude at the mountain village of Sormano in the pre-Alps, the observatory was privately funded by the Gruppo Astrofili Brianza and built in 1986.
Felix Hormuth (born 1975) is a German astronomer, working at the Max Planck Institute for Astronomy (MPIA) until 2016, and a prolific discoverer of minor planets. During his stay at the Calar Alto Observatory in Spain, he has discovered many asteroids, including a Jupiter trojan and two near-Earth objects, such as the 15-meter Amor asteroid 2009 DS36, using MPIA's 1.23-meter reflector telescope.
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 CD3 (also 2020CD3 or CD3 for short) is a tiny near-Earth asteroid (or minimoon) that ordinarily orbits the Sun but makes close approaches to the Earth–Moon system, in which it can temporarily enter Earth orbit through temporary satellite capture (TSC). It was discovered at the Mount Lemmon Observatory by astronomers Theodore Pruyne and Kacper Wierzchoś on 15 February 2020, as part of the Mount Lemmon Survey or Catalina Sky Survey. The asteroid's discovery was announced by the Minor Planet Center on 25 February 2020, after subsequent observations have confirmed that it was orbiting Earth.
