Felix Hormuth
Felix Hormuth (born 1975) is a German astronomer, working at the Max Planck Institute for Astronomy (MPIA) until 2016, and a prolific discoverer of minor planets. During his stay at the Calar Alto Observatory in Spain, he has discovered many asteroids, including a Jupiter trojan and two near-Earth objects, such as the 15-meter Amor asteroid , using MPIA's 1.23-meter reflector telescope. Career Hormuth has worked with data obtained by the Infrared Space Observatory, was involved in the measurement campaign of the Very Large Telescope's GRAVITY-interferometer, and participated in the construction of optical instruments used at the NTT in La Silla, Chile. As of 2016, he is a project manager at MPIA, working for the Institute's hardware contribution to ESA's space-based Euclid mission, which will accurately measure the acceleration of the universe for the study of dark energy and dark matter. The Minor Planet Center ranks him 127th for a total of 75 credited discoveries of number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Jet Propulsion Laboratory
The Jet Propulsion Laboratory (JPL) is a federally funded research and development center and NASA field center in the City of La Cañada Flintridge, California, United States. Founded in the 1930s by Caltech researchers, JPL is owned by NASA and managed by the nearby California Institute of Technology (Caltech). The laboratory's primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating the NASA Deep Space Network. Among the laboratory's major active projects are the Mars 2020 mission, which includes the ''Perseverance'' rover and the '' Ingenuity'' Mars helicopter; the Mars Science Laboratory mission, including the ''Curiosity'' rover; the InSight lander (''Interior Exploration using Seismic Investigations, Geodesy and Heat Transport''); the ''Mars Reconnaissance Orbiter''; the ''Juno'' spacecraft orbiting Jupiter; the ''SMAP'' satellite for earth surface s ...

342843 Davidbowie
342843 Davidbowie, provisional designation , is a Henan asteroid from the central region of the asteroid belt, approximately 1.4 kilometers in diameter. The asteroid was discovered on 21 December 2008, by German astronomer Felix Hormuth from Max-Planck-Institute for Astronomy at Calar Alto Observatory in Almería, southeastern Spain. It was named for British singer-songwriter David Bowie. Orbit and classification ''Davidbowie'' is a member of the Henan family (), a large family of L-type asteroids in the intermediate main-belt, named after 2085 Henan. It orbits the Sun in the central asteroid belt at a distance of 2.5–3.0 AU once every 4 years and 7 months (1,665 days; semi-major axis of 2.75 AU). The asteroid has a well-observed orbit with the lowest possible condition code. Its orbit has an eccentricity of 0.09 and an inclination of 3 ° with respect to the ecliptic. It was first identified as at the Steward Observatory (Kitt Peak) in September 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnitude (astronomy)
In astronomy, magnitude is a unitless measure of the brightness Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. In other words, brightness is the perception elicited by the luminance of a visual target. The perception is not linear to luminance, ... of an astronomical object, object in a defined passband, often in the visible spectrum, visible or infrared spectrum, but sometimes across all wavelengths. An imprecise but systematic determination of the magnitude of objects was introduced in ancient times by Hipparchus. The scale is Logarithmic scale, logarithmic and defined such that a magnitude 1 star is exactly 100 times brighter than a magnitude 6 star. Thus each step of one magnitude is \sqrt[5] \approx 2.512 times brighter than the magnitude 1 higher. The brighter an object appears, the lower the value of its magnitude, with the brightest objects reaching negative values. Astronomers use two different defini ...

Lutz Schmadel
Lutz Dieter Schmadel (2 July 1942, in Berlin – 21 October 2016) was a German astronomer and a prolific discoverer of asteroids, who worked at the Astronomisches Rechen-Institut (ARI) of the University of Heidelberg. His special interest was the astrometry of minor planets. Among his numerous discoveries were the three main-belt asteroids 8661 Ratzinger, 10114 Greifswald and 11508 Stolte. He was the author of the Dictionary of Minor Planet Names, a reference book containing information about the discovery and naming of 12,804 asteroids (March 2006). One asteroid 2234 Schmadel, discovered in 1977, was named in his honor. The asteroid 8811 Waltherschmadel was named for his father, Walther Schmadel (1902–1944), who died at the Eastern Front near Stalingrad during WWII. Discoveries Lutz Schmadel is credited by the Minor Planet Center with the discovery of 245 minor planet According to the International Astronomical Union (IAU), a minor planet is an astronomical ob ...
