Jeff T. Alu
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. He also co-discovered 117P/Helin–Roman–Alu and 132P/Helin–Roman–Alu, two 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).

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 Comets
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] |

(17511) 1992 QN
(17511) 1992 QN (Minor planet provisional designation, provisional designation ) is a small, bright Apollo asteroid discovered on August 29, 1992 by American astronomers Eleanor F. Helin, Eleanor Helin and Jeff T. Alu, Jeff Alu at the Palomar Observatory, California, United States. It is a near-Earth asteroid whose orbit crosses that of Mars and Earth (a Mars and Earth-crossing asteroid). On January 18, 1996, it passed Earth at a distance of 0.158848 Astronomical unit, AU (23.763 million km), and on July 12, 2027, it will pass our planet again at a distance of 0.161858 AU (24.214 million km).

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 . 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 can be difficult to calcul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kenneth J
Kenneth is a given name of Gaelic origin. The name is an Anglicised form of two entirely different Gaelic personal names: ''Cainnech'' and '' Cináed''.

Etymology The second part of the name ''Cinaed'' is derived either from the Celtic ''*aidhu'', meaning "fire", or else Brittonic ''jʉ:ð'' meaning "lord".

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 t ... [...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 dialect, Provençal name ''Aliénor''. It was the name of a number of women of royalty and nobility in western Europe during the High Middle Ages.

The name was popular in the Anglosphere during the first half of the 20th century, but declined in use until the late 20th century and first decades of the 21st century. It has been a well-used name in the United States, Canada, the United Kingdom, Australia and New Zealand during the 2020s. Eleanor was the third most popular name for newborn girls born to White Americans, white mothers in the U.S. state of Virginia in 2024, but was a less popular name for ...
