(718492) Quro, provisional designation 2017 FZ233, is a main-belt asteroid. It was discovered on 22 March 2017, by the citizen science project Come On! Impacting ASteroids (COIAS) [1] using archival data from the Subaru Telescope, [3] which was first reported to the Minor Planet Center in 2024.
Quro orbits the Sun within the main asteroid belt with a semimajor axis of about 3.2 AU and an inclination of about 8 degrees from the ecliptic plane. It has a fairly circular orbit with an eccentricity of about 0.057. It completes an orbit around the Sun about every 5.6 years. [1]
Quro has been observed for the first time by the Subaru Telescope in 2012, later by the Cerro Tololo Inter-American Observatory in 2014, and later again by the Subaru Telescope in 2017. Pan-STARRS and Kitt Peak National Observatory have observed Quro between the years 2019 and 2023. These observations altogether made it possible to refine the orbit determination of the asteroid well enough to give it an orbital uncertainty parameter of 0 by the Minor Planet Center. [1]
Although the asteroid first appeared in an 2012 observation, the astrometric measurements of 2017 sightings were made and submitted to the MPC earlier, thus being assigned as the discovery observations per MPC regulations. [4] These measurements were done by citizen scientists taking part in COIAS (Come On! Impacting ASteroids) project, [5] giving the opportunity to the project team and the measurers an opportunity to propose a name for the numbered asteroid. It was named after the author of the comic work Asteroid in Love (original title shortened as "Koias", to which the name of the project "COIAS" references), with the naming citation published as follows:
Quro (b. 1985) is a Japanese manga artist who created the comic Asteroid in Love. Real astronomical events and institutes appear in the work as models. Thanks to “Chura Ken”, an event held on Ishigakijima Island, finding new asteroids and astronomical phenomena has become popular among young students, giving them real research experiences. [2]
Lowell Observatory Near-Earth-Object Search (LONEOS) was a project designed to discover asteroids and comets that orbit near the Earth. The project, funded by NASA, was directed by astronomer Ted Bowell of Lowell Observatory in Flagstaff, Arizona. The LONEOS project began in 1993 and ran until the end of February 2008.
Marc William Buie is an American astronomer and prolific discoverer of minor planets who works at the Southwest Research Institute in Boulder, Colorado in the Space Science Department. Formerly he worked at the Lowell Observatory in Flagstaff, Arizona, and was the Sentinel Space Telescope Mission Scientist for the B612 Foundation, which is dedicated to protecting Earth from asteroid impact events.
524522 Zoozve (provisional designation 2002 VE68) is a sub-kilometer sized asteroid and temporary quasi-satellite of Venus. Discovered in 2002, it was the first such object to be discovered around a major planet in the Solar System. It has nearly the same orbital period around the Sun that Venus does. In a frame of reference rotating with Venus, it appears to travel around it during one Venerean year, but it orbits the Sun, not Venus.

It was discovered on 22 August 1985, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona, United States. The asteroid was named after Canadian astronomer David H. Levy.
3708 Socus (provisional designation: 1974 FV1) is a large Jupiter trojan from the Trojan camp, approximately 77 kilometers (48 miles) in diameter. It was discovered on 21 March 1974, by staff members of the Cerro El Roble Observatory owned and operated by the Department of Astronomy of the University of Chile. The assumed C-type asteroid has a rotation period of 6.55 hours. It was named after Socus, a hero from Greek mythology, who was killed in battle by Odysseus.
1912 Anubis is a stony Koronis asteroid from the outer region of the asteroid belt, approximately 10 kilometers in diameter. It was named after the Egyptian deity Anubis.
2134 Dennispalm, provisional designation 1976 YB is a main-belt asteroid discovered on December 24, 1976, by Charles T. Kowal at Palomar Observatory.
7816 Hanoi, provisional designation 1987 YA, is an eccentric stony asteroid and Mars-crosser from the inner regions of the asteroid belt, approximately 3 kilometers in diameter. It was discovered on 18 December 1987, by Japanese astronomer Masahiro Koishikawa at the Ayashi Station of the Sendai Astronomical Observatory, Japan, and later named after the Vietnamese capital of Hanoi.
11132 Horne is a Hygiean asteroid from the outer regions of the asteroid belt, approximately 13 kilometers in diameter. It was discovered on 17 November 1996, by American amateur astronomer Dennis di Cicco at his Sudbury Observatory in Massachusetts, United States. The asteroid was named for Johnny Horne, photo editor of The Fayetteville Observer.
6500 Kodaira, provisional designation 1993 ET, is a highly eccentric, rare-type asteroid and sizable Mars-crosser from the central regions of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 15 March 1993, by Japanese amateur astronomers Kin Endate and Kazuro Watanabe at Kitami Observatory in eastern Hokkaidō, Japan. It was named for Japanese astronomer Keiichi Kodaira.
2577 Litva, provisional designation 1975 EE3, is a Hungarian-type Mars-crosser and rare trinary asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter.
5119 Imbrius, provisional designation:1988 RA1, is a Jupiter trojan from the Trojan camp, approximately 49 kilometers (30 mi) in diameter. It was discovered on 8 September 1988 by Danish astronomer Poul Jensen at the Brorfelde Observatory near Holbæk, Denmark. The dark Jovian asteroid has a rotation period of 12.8 hours. It was numbered in March 1992, and named from Greek mythology after Imbrius, who was killed by Greek archer Teucer during the Trojan War.
6002 Eetion, provisional designation: 1988 RO, is a mid-sized Jupiter trojan from the Trojan camp, approximately 40 kilometers in diameter. It was discovered by Poul Jensen at the Brorfelde Observatory in 1988, and has not been named since its numbering in June 1994. The dark Jovian asteroid has a rotation period of 12.9 hours. In 2021, it was named from Greek mythology after King Eetion, who was killed by Achilles during the raid on Thebe.
7641 Cteatus, provisional designation: 1986 TT6, is a large Jupiter trojan from the Greek camp, approximately 70 kilometers (43 miles) in diameter.

152830 Dinkinesh (provisional designation 1999 VD57) is a binary main-belt asteroid about 790 meters (2,600 feet) in diameter. It was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) survey at Socorro, New Mexico on 4 November 1999.

During the flyby, the Lucy spacecraft discovered that Dinkinesh has a contact-binary natural satellite, named Selam, which is 220 meters (720 ft) in diameter. Dinkinesh is the smallest main-belt asteroid explored by spacecraft yet, though some smaller near-Earth asteroids have also been explored.
