It was discovered on 4 February 1932, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle. The asteroid was named after Adolphe Quetelet, a Belgian astronomer and mathematician. Discovery Queteleta was discovered on 4 February 1932, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle. It was independently discovered by Louis Boyer at Algiers Observatory, Algeria, on the same night and by George Van Biesbroeck at Yerkes Observatory, United States, on 13 February 1932. The Minor Planet Center only recognizes the first mentioned discoverer. Orbit and classification Queteleta is a non-family asteroid from the main belt's background population. It orbits the Sun in the central main-belt at a distance of 2.0–3.3 AU once every 4 years and 4 months (1,585 days; semi-major axis of 2.66 AU). Its orbit has an eccentricity of 0.23 and an inclination of 2° with respect to the ecliptic. The body's observation arc begins at with its official discovery observation at Uccle in 1932. Physical characteristics The asteroid's spectral type has not been determined, but its low albedo (see below) is typical for that of a carbonaceous C-type asteroid. Diameter and albedo According to the surveys carried out by the Infrared Astronomical Satellite IRAS and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Queteleta measures 15.94 and 18.032 kilometers in diameter and its surface has an albedo of 0.0695 and 0.051, respectively. Rotation period, poles and shape As of 2018, no rotational lightcurve of Queteleta has been obtained from photometric observations. The asteroid's rotation period, shape and poles remain unknown. Naming This minor planet was named after Belgian astronomer and mathematician Adolphe Quetelet (1796–1874), whose research also encompassed several other scientific disciplines such as statistics, demography, sociology, criminology and the history of science. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 114). He was also honored by the lunar crater Quetelet. References 30em 2017-11-24 last obs.
