1410 Margret, provisional designation1937 AL, is an Eoanasteroid from the outer regions of theasteroid belt, approximately 21 kilometers in diameter. It was discovered on 8 January 1937, by astronomerKarl Reinmuth at theHeidelberg Observatory in southwest Germany.[5] The asteroid was named after Margret Braun, wife of the Heidelberg astronomerHeinrich Vogt.[2]
Margret is a member of theEos family (606),[3] the largestasteroid family in theouter main belt consisting of nearly 10,000 asteroids.[6]: 23
It orbits the Sun at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,917 days). Its orbit has aneccentricity of 0.11 and aninclination of 10° with respect to theecliptic.[1]
The body'sobservation arc begins with its first identification asA924 RD atSimeiz Observatory in September 1924, more than 12 years prior to its official discovery observation at Heidelberg.[5]
The asteroid'sspectral type is unknown.[1] The Eos family typically consists ofK-type asteroids.[6]: 23
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Margret measures 21.083 kilometers in diameter and its surface has analbedo of 0.145,[4] which agrees with the albedo of 0.14 measured for the parent body of the Eos family,221 Eos.
As of 2017, no rotationallightcurve ofMargret has been obtained from photometric observations. The asteroid'srotation period, spin axis and shape remain unknown.[7]
Thisminor planet was named after Margret Braun (died 1991), wife of the Heidelberg astronomerHeinrich Vogt (1890–1968), after whom1439 Vogtia was named. The subsequently numbered asteroid1411 Brauna is also named after Margret Braun. The official naming citation was mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 127).[2]
