1588 Descamisada, provisional designation 1951 MH, is an asteroid from the outer region of the asteroid belt, roughly about 25 kilometers in diameter. It was discovered on 27 June 1951, by astronomer Miguel Itzigsohn at the La Plata Astronomical Observatory in La Plata, Argentina.[4]
The asteroid orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,925 days). Its orbit shows an eccentricity of 0.07 and is tilted by 11 degrees to the plane of the ecliptic.[1] Little is known about the asteroids size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty – which is denoted by a condition code of 0 – and an observation arc that spans over a period of more than 60 years.[1] With an absolute magnitude of 11.3, the asteroid's diameter could be anywhere between 14 and 36 kilometers for an assumed albedo in the range of 0.05–0.25 (see NASA's conversion table).[3] Since outer main-belt asteroids typically have a spectral type of a darker carbonaceous, rather than a brighter rocky body, its true diameter may be at the upper end of NASA's generic conversion table, as an object's diameter increases, when its albedo decreases, for a given absolute magnitude.[3]
The minor planet was named for Eva 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 of Peronism. Eva Perón, also known as "Evita", was the wife of Argentine President Juan Perón, First Lady of Argentina and idolized by millions. The asteroids 1569 Evita, 1581 Abanderada, 1582 Martir and 1589 Fanatica were also discovered by Itzigsohn, and were also given names in tribute to Perón.[2]
