Yrjö Väisälä was a Finnish astronomer and physicist.
Near-Earth Asteroid Tracking (NEAT) was a program run by NASA and the Jet Propulsion Laboratory, surveying the sky for near-Earth objects. NEAT was conducted from December 1995 until April 2007, at GEODSS on Hawaii, as well as at Palomar Observatory in California. With the discovery of more than 40 thousand minor planets, NEAT has been one of the most successful programs in this field, comparable to the Catalina Sky Survey, LONEOS and Mount Lemmon Survey.
The Spacewatch Project is an astronomical survey that specializes in the study of minor planets, including various types of asteroids and comets at University of Arizona telescopes on Kitt Peak near Tucson, Arizona, in the United States. The Spacewatch Project has been active longer than any other similar currently active programs.
Catalina Sky Survey is an astronomical survey to discover comets and asteroids. It is conducted at the Steward Observatory's Catalina Station, located near Tucson, Arizona, in the United States.
Hendrik van Gent was a Dutch astronomer.
Roy A. Tucker (1951 – 2021) was an American astronomer best known for the co-discovery of near-Earth asteroid 99942 Apophis (formerly known as 2004 MN4) along with David J. Tholen and Fabrizio Bernardi of the University of Hawaii. He was a prolific discoverer of minor planets, credited by the Minor Planet Center with the discovery of 702 numbered minor planets between 1996 and 2010. He also discovered two comets: 328P/LONEOS–Tucker and C/2004 Q1, a Jupiter-family and near-parabolic comet, respectively.
Masaru Arai is a Japanese amateur astronomer and a discoverer of minor planets and comets.
Ernest Leonard Johnson (1891–1977) was a South African astronomer and a former staff member of the Union Observatory in Johannesburg, South Africa. He is known for the discovery of 18 asteroids between 1946–1951, as well as several comets. On 25 August 1949, he discovered 48P/Johnson, a periodic comet expected to pass no closer than 1.2 to 1.3 AU from our planet in 2025. Johnson received the "Donohoe Comet Medal" twice before retiring in 1956. He died in 1977.
Alfred Schmitt was a French astronomer. Schmitt worked at Algiers Observatory in the 1930s and 1940s and at the Royal Observatory in Uccle, Belgium in the 1950s. From 1955 to 1958 he was also director of the Quito Observatory in Ecuador. He extensively studied minor planets and comets and is credited with having discovered four asteroids.
Jeffrey S. Medkeff, usually known as Jeff Medkeff, was a prominent science writer and educator. He was also a designer of robotic telescopes, a minor philanthropist, and an advocate of personal and sexual freedom.
James Whitney Young is an American astronomer who worked in the field of asteroid research. After nearly 47 years with the Jet Propulsion Laboratory at their Table Mountain Facility, Young retired July 16, 2009.
Stephen J. Edberg is a scientist at the Jet Propulsion Laboratory. He is perhaps best known for creating collaborative efforts between amateur and professional astronomers. A professional astronomer since 1970, Edberg still considers himself to be an active amateur astronomer as well and is an active astronomical observer, photographer, and telescope maker. He presently serves as staff astronomer for the Solar System Exploration website posted by NASA Headquarters and staff scientist for Earth science communication and for Exoplanet Exploration communication.
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.
7529 Vagnozzi, provisional designation 1994 BC, is a stony asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 16 January 1994, by and at the Colleverde Observatory near Rome, Italy. The asteroid was named for was named for Italian amateur astronomer Antonio Vagnozzi.
51983 Hönig (provisional designation 2001 SZ8) is a Hildian asteroid from the outermost regions of the asteroid belt, approximately 13 kilometers in diameter. It was discovered on 19 September 2001, by astronomers Charles Juels and Paulo Holvorcem at the Fountain Hills Observatory (678) in Arizona, United States. The asteroid was named after German astronomer Sebastian Hönig.
