Английская Википедия:1823 Gliese
1823 Gliese, provisional designation Шаблон:Mp, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 4 September 1951, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany.[1] The asteroid was named after German astronomer Wilhelm Gliese.[2]
Orbit and classification
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,213 days). Its orbit has an eccentricity of 0.14 and an inclination of 3° with respect to the ecliptic.[3] The first unused observations date back to 1944 at Johannesburg Observatory, when it was identified as Шаблон:Mp. The first used precovery was taken at the discovering Heidelberg observatory in 1950, extending the asteroid's observation arc by one year prior to its official discovery.[1]
Physical characteristics
Rotation period
A rotational lightcurve of this asteroid was obtained from photometric observations made by Czech astronomer Petr Pravec at the Ondřejov Observatory in August 2014. The lightcurve gave a well-defined rotation period of Шаблон:Val hours with a brightness variation of 0.27 in magnitude (Шаблон:Small).Шаблон:Efn One month later, in September 2014, a second lightcurve by American astronomer Brian Warner at his Palmer Divide Observatory, Colorado, gave a concurring period of Шаблон:Val hours with an amplitude of 0.23 in magnitude (Шаблон:Small).[4]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 8.4 and 9.5 kilometers in diameter and its surface has an albedo of 0.189 and 0.135, respectively,[5][6] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of this asteroid's orbital family – and calculates a diameter of 8.2 kilometers with an absolute magnitude of 12.6.[7]
Naming
This minor planet was named after German astronomer Wilhelm Gliese (1915–1993) at the Astronomisches Rechen-Institut. Gliese is widely known for having compiled about 1,000 stars located within 25 parsecs of Earth into the Gliese Catalogue of Nearby Stars.[2] The official Шаблон:MoMP was published by the Minor Planet Center on 18 April 1977 (Шаблон:Small).[8] A large number of Exoplanets derive their names form this star catalogue.
