Английская Википедия:1169 Alwine
1169 Alwine, provisional designation Шаблон:Mp, is a Florian asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 30 August 1930, by German and Italian astronomers Max Wolf and Mario Ferrero at Heidelberg Observatory in southwest Germany.[1] Any reference of its name to a person is unknown.[2]
Orbit and classification
Alwine is a member of the Flora family (Шаблон:Small),[3] a giant asteroid family and the largest family of stony asteroids in the main belt.[4]Шаблон:Rp It orbits the Sun in the inner asteroid belt at a distance of 2.0–2.7 AU once every 3 years and 6 months (1,290 days; semi-major axis of 2.32 AU). Its orbit has an eccentricity of 0.15 and an inclination of 4° with respect to the ecliptic.[5] As no precoveries were taken, and no prior identifications were made, AlwineШаблон:'s observation arc begins with its official discovery observation at Heidelberg in August 1930.[1]
Physical characteristics
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Alwine measures 7.89 kilometers in diameter, and its surface has an albedo of 0.179.[6] Based on a generic magnitude-to-diameter conversion, its diameter is between 7 and 17 kilometers for an absolute magnitude of 12.8 and an albedo in the range of 0.05 to 0.25.[7]
Lightcurve
As of 2017, no rotational lightcurves have been obtained. The body's rotation period, pole and shape remain unknown.[5][8]
Naming
This minor planet is named after a common German female name. Any reference of this name to a person or occurrence is unknown.[2]
Unknown meaning
Among the many thousands of named minor planets, Alwine is one of 120 asteroids, for which no official naming citation has been published. All of these low-numbered asteroids have numbers between Шаблон:Mp and Шаблон:Mp and were discovered between 1876 and the 1930s, predominantly by astronomers Auguste Charlois, Johann Palisa, Max Wolf and Karl Reinmuth.[9]
