1569 Evita (provisional designation1948 PA) is a dark backgroundasteroid from the outer regions of theasteroid belt, approximately 36 kilometers in diameter. It was discovered on 3 August 1948, by astronomerMiguel Itzigsohn at theLa Plata Astronomical Observatory in Argentina.[6] The asteroid was named afterEva Perón.[2]
Based on thehierarchical clustering method, Evita is a non-family asteroid of the main belt'sbackground population.[3] It orbits the Sun in theouter main-belt at a distance of 2.7–3.6 AU once every 5 years and 7 months (2,039 days). Its orbit has aneccentricity of 0.13 and aninclination of 12° with respect to theecliptic.[1]
The asteroid was first identified as1936 KE at theJohannesburg Observatory in May 1936. The body'sobservation arc begins with its official discovery observation at La Plata.[6]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, Evita measures 36.346 kilometers in diameter and its surface has analbedo of 0.047.[4][5] An albedo near 0.05 is typical for carbonaceousC-type asteroids which dominate the outer asteroid belt. It has anabsolute magnitude of 11.2.[1]
As of 2017, no rotationallightcurve of Evita has been obtained from photometric observations. The asteroid'srotation period andaxis, as well as its shape remain unknown.[7]
Thisminor planet was named after the First Lady of Argentina,Eva Perón (1919–1952), who was commonly known by the affectionate Spanish diminutive form of her name, Evita. She was the wife of PresidentJuan Perón (1895–1974) of Argentina.[2]
The discoverer also named the asteroids1581 Abanderada,1582 Martir,1588 Descamisada and1589 Fanatica in tribute to Eva Perón.[2] The officialnaming citation was published by theMinor Planet Center in February 1951 (M.P.C. 519).[8]
