14832 Alechinsky, provisional designation 1987 QC3, is a stony asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 27 August 1987, by Belgian astronomer Eric Elst at ESO's La Silla Observatory site in northern Chile.[7]
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.0–2.6 AU once every 3 years and 6 months (1,268 days). Its orbit is tilted by 6° to the plane of the ecliptic and shows an eccentricity of 0.12.[1]
The body has an albedo of 0.24, as assumed by the Collaborative Asteroid Lightcurve Link (CALL), with a calculated diameter of 4.1 kilometers,[3] while the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer finds an albedo of 0.19 and a corresponding diameter of 4.4 kilometers.[4]
Two rotational light-curves obtained at the U.S. Palomar Transient Factory, California, gave a rotation period of 8.07±0.02 and 9.5831±0.1453 hours, with a high brightness variation of 0.98 and 1.30 in magnitude, respectively (U=2+/2).[5][6] This typically indicates that the body has an elongated shape.
The minor planet was named after Belgian painter Pierre Alechinsky (b. 1927). He founded the expressionist movement "CoBRa", a name linking the cities of Copenhagen, Brussels and Amsterdam. He was one of the leading artist of mid-Century Europe, and is well known for his treatment of colors, versatility and graphic humor.[2]
