Dennis Di Cicco
Dennis di Cicco (born 1950) is an American amateur astronomer and a discoverer of minor planets, who lives in New England. He has discovered 60 numbered asteroids from his backyard observatory in Sudbury, Massachusetts (IAU code: IAU code#817, 817). He was a member of the editorial staff of ''Sky and Telescope'' magazine from 1974 until his resignation as senior editor in June 2014. His special interests include astronomical photography and the history of astronomical photography, telescope making, and astronomical observing. During 1978 and 1979 he was the first person to successfully photograph the analemma, making 48 separate exposures on a single piece of film during a 12-month period. The project is described in the June 1979 issue of ''Sky & Telescope''. The asteroid 3841 Dicicco was named after him. Di Cicco conducted observations and calculations to determine the exact time and date of Ansel Adams’ famous 1941 photograph, ''Moonrise, Hernandez, New Mexico''. He grew up ...

Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting IAU definition of planet, reclassified minor planets and comets into dwarf planets and Small Solar System body, small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006. Accessed May 5, 2008. In contrast to the eight official planets of the Solar System, all minor planets fail to clearing the neighborhood, clear their orbital neighborhood.

Discoverers Of Asteroids
Discovery is the act of detecting something new, or something previously unrecognized as meaningful, "portal". In sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and involves providing new reasoning to explain the knowledge gathered through such observations, using knowledge previously acquired through abstract thought and from everyday experiences. Some discoveries represent a radical breakthrough in knowledge or technology. Others are based on earlier discoveries, collaborations or ideas. In such cases, the process of discovery requires at least the awareness that an existing concept or method could be modified or transformed. New discoveries are made using various senses, and are usually added to pre-existing knowledge. Questioning plays a key role in discovery; discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. Science Within scientific discip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
11132 Horne
11132 Horne ( provisional designation ) is a Hygiean asteroid from the outer regions of the asteroid belt, approximately 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''. Orbit and classification Horne is a member of the Hygiea family (), a very large family of carbonaceous outer-belt asteroids, named after the fourth-largest asteroid, 10 Hygiea. It orbits the Sun in the outer asteroid belt at a distance of 2.8–3.5 AU once every 5 years and 7 months (2,035 days; semi-major axis of 3.14 AU). Its orbit has an eccentricity of 0.11 and an inclination of 4 ° with respect to the ecliptic. The body's observation arc begins with its first observation at Siding Spring Observatory in April 1993, more than 3 years prior to its official discovery observation. Physi ...

9983 Rickfienberg
9983 Rickfienberg ( ''prov. designation'': ) is a carbonaceous asteroid from the middle region of the asteroid belt, approximately in diameter. It was discovered on 19 February 1995, by American astronomer Dennis di Cicco at his private Sudbury Observatory , Massachusetts, United States. It was named after American astronomer and editor Richard Fienberg. Orbit and classification ''Rickfienberg'' is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. The dark C-type asteroid orbits the Sun in the central main-belt at a distance of 2.4–3.0 AU once every 4 years and 5 months (1,627 days). Its orbit has an eccentricity of 0.12 and an inclination of 8 ° with respect to the ecliptic. The first observation was taken at the Australian Siding Spring Observatory in 1987, extending the asteroid's observation arc by 8 years prior to its discovery. Naming This minor planet was nam ...
