14832 Alechinsky, provisional designation 1987 QC3, is a stony asteroid from the inner regions of the asteroid belt, about 4 kilometers in diameter. It was discovered by Belgian astronomer Eric Elst at ESO's La Silla Observatory in northern Chile on 27 August 1987.[6]
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 degrees to the plane of the ecliptic and shows an eccentricity of 0.12. The body has an albedo of 0.24, as assumed by the Collaborative Asteroid Lightcurve Link (CALL). Two different observations from the Palomar Transient Factory rendered a rotation period of 8.1 and 9.6 hours, respectively.[4][5]
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]
