It was discovered on 30 August 1930, by German and Italian astronomers Max Wolf and Mario Ferrero at Heidelberg Observatory in southwest Germany.[8] Any reference of its name to a person is unknown.[2] Orbit and classificationAlwine is a member of the Flora family ({{small|402}}),[3] a giant asteroid family and the largest family of stony asteroids in the main belt.[11]{{rp|23}} 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. As no precoveries were taken, and no prior identifications were made, Alwine{{'}}s observation arc begins with its official discovery observation at Heidelberg in August 1930.[8]Physical characteristicsAccording 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.[5] 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.[15] LightcurveAs of 2017, no rotational lightcurves have been obtained. The body's rotation period, pole and shape remain unknown.[17] NamingThis minor planet is named after a common German female name. Any reference of this name to a person or occurrence is unknown.[2] Unknown meaningAmong 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 {{mp|{{MoMP|164|164 Eva}}}} and {{mp|{{MoMP|1514|1514 Ricouxa}}}} and were discovered between 1876 and the 1930s, predominantly by astronomers Auguste Charlois, Johann Palisa, Max Wolf and Karl Reinmuth (also see category).[19] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1169) Alwine |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 98 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1170 |chapter = (1169) Alwine }} [1][2][3][4][5][6][7][8]2. ^1 {{cite book |title = Dictionary of Minor Planet Names – Fifth Revised and Enlarged revision |chapter = Appendix 11 – Minor Planet Names with Unknown Meaning |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |pages = 927–929 |date = 2007 |isbn = 978-3-540-00238-3 |author-link= Lutz D.
