Jeffrey (Jeff) Thomas Alu (born January 1, 1966) is an American musician, photographer, graphic artist, and amateur astronomer who has participated in the Palomar Planet-Crossing Asteroid Survey. The asteroid 4104 Alu was named in his honor. Discoveries Alu is credited by the Minor Planet Center with the discovery of 24 minor planets, including several near-Earth asteroids as well as some in the asteroid belt. Many of these discoveries were made in collaboration with American astronomers Eleanor F. Helin and Kenneth J. Lawrence.

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 reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006.

Discoverers Of Comets
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. With reference to sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences. A discovery may sometimes be based on earlier discoveries, collaborations, or ideas. Some discoveries represent a radical breakthrough in knowledge or technology. New discoveries are acquired through various senses and are usually assimilated, merging with pre-existing knowledge and actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. A discovery may sometimes be based on earlier discoveries, collabo ...

(17511) 1992 QN
(17511) 1992 QN is a small, bright Apollo asteroid discovered on August 29 1992 by American astronomers Eleanor Helin and Jeff Alu at the Palomar Observatory, California, United States. It is a near-Earth asteroid whose orbit crosses that of Mars and Earth Earth is the third planet from the Sun and the only astronomical object known to harbor life.

Periodic Comet
Periodic comets (also known as short-period comets) are comets with orbital periods of less than 200 years or that have been observed during more than a single perihelion passage (e.g. 153P/Ikeya–Zhang). "Periodic comet" is also sometimes used to mean any comet with a periodic orbit, even if greater than 200 years. Periodic comets receive a permanent number prefix usually after the second perihelion passage, which is why there are a number of unnumbered periodic comets, such as P/2005 T5 (Broughton). Comets that are not observed after a number of perihelion passages, or presumed to be destroyed, are given the D designation, and likewise comets given a periodic number and subsequently lost are given instead of , such as 3D/Biela or 5D/Brorsen. In nearly all cases, comets are named after their discoverers, but in a few cases such as 2P/Encke and 27P/Crommelin they were named for a person who calculated their orbits (the orbit computers). The long-term orbits of comets ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amateur Astronomer
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies. Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists, while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Many astronomers have studied the sky throughout history in an amateur framework; however, since the beginning of the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleanor F
Eleanor () is a feminine given name, originally from an Old French adaptation of the Old Provençal name ''Aliénor''. It is the name of a number of women of royalty and nobility in western Europe during the High Middle Ages. The name was introduced to England by Eleanor of Aquitaine, who came to marry King Henry II. It was also borne by Eleanor of Provence, who became Queen consort of England as the wife of King Henry III, and Eleanor of Castile, wife of Edward I. The name was popular in the United States in the 1910s and 1920s, peaking at rank 25 in 1920. It declined below 600 by the 1970s, again rose to rank 32 in the 2010s. Eleanor Roosevelt, the longest-serving first lady of the US was probably the most famous bearer of the name in contemporary history. Common hypocorisms include Elle, Ella, Ellie, Elly, Leonor, Leonora, Leonore, Nella, Nellie, Nelly, and Nora.
