    1589 Fanatica, provisional designation 1950 RK, is a stony, Vesta-like asteroid from the inner regions of the asteroid belt, about 12 kilometers in diameter. It was discovered on 13 September 1950, by Argentine astronomer Miguel Itzigsohn at La Plata Astronomical Observatory, La Plata, capital of the province of Buenos Aires.[9]

    The Collaborative Asteroid Lightcurve Link classifies the S-type asteroid as a vestoid, based on its orbital elements similar to that of 4 Vesta, the third largest body in the main-belt after the dwarf planet 1 Ceres and the minor planet 2 Pallas. Fanatica orbits the Sun at a distance of 2.2–2.6 AU once every 3 years and 9 months (1,372 days). Its orbit shows an eccentricity of 0.09 and is tilted by 5 degrees to the plane of the ecliptic. The body rotates around it axis every 2.58 hours[7][8] and has an albedo of 0.19–0.26, according to the surveys carried out by the space-based Akari and WISE/NEOWISE missions.[4][5][6]

    The minor planet was named in reference to Argentine legend, Eva Perón (1919–1952), also known as "Evita", wife of Argentine President Juan Perón, First Lady of Argentina and idolized by millions.[2] The asteroids 1569 Evita, 1581 Abanderada, 1582 Martir and 1588 Descamisada were also discovered by Itzigsohn, and were also given names in tribute to Perón.
