1588 Descamisada, provisional designation1951 MH, is anEos asteroid from the outer region of theasteroid belt, approximately 18 kilometers in diameter. It was discovered on 27 June 1951, by astronomerMiguel Itzigsohn at theLa Plata Astronomical Observatory in La Plata, Argentina, and named in honor ofEva Perón.[2][6]
Descamisada is a member of theEos family (606), the largestasteroid family in theouter main belt consisting of nearly 10,000 asteroids.[3][7]: 23 It orbits the Sun in theouter main-belt at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,924 days). Its orbit has aneccentricity of 0.07 and aninclination of 11° with respect to theecliptic.[1]Descamisada'sobservation arc begins with its official discovery observation, as noprecoveries were taken and no prior identifications were made.[6]
According to the surveys carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Descamisada measures 17.54 kilometers in diameter and its surface has analbedo of 0.141.[4] Amagnitude-to-diameter conversion, gives a diameter between 14 and 36 kilometers for an assumedalbedo in the range of 0.05–0.25 and an absolute magnitude of 11.3.[5]
As of 2017,Descamisada'sspectral type,rotation period and shape remain unknown.[8]
Thisminor planet was named forEva Perón and its name is a feminized form of "descamisado" (shirtless one) – a term used to denote the working class citizens which formed the support base ofPeronism. Eva Perón, also known as "Evita", was the wife of Argentine President Juan Perón, First Lady of Argentina and idolized by millions.[2] The officialnaming citation was published by theMinor Planet Center in April 1954 (M.P.C. 1069).[9] The asteroids1569 Evita,1581 Abanderada,1582 Martir and1589 Fanatica were also discovered by Itzigsohn, and were also given names in tribute to Perón.[2]
