    1633 Chimay, provisional designation 1929 EC, is a Themistian asteroid from the outer region of the asteroid belt, approximately 37 kilometers in diameter.

    Contents

    It was discovered on 3 March 1929, by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle. [13] Five nights later, the body was independently discovered by Max Wolf at Heidelberg Observatory in southern Germany. [2] It was later named for the Belgian town of Chimay. [2]

    Classification and orbit

    Chimay is a member of the Themis family, a dynamical family of asteroids with nearly coplanar ecliptical orbits. It orbits the Sun in the outer main-belt at a distance of 2.8–3.6  AU once every 5 years and 9 months (2,085 days). Its orbit has an eccentricity of 0.12 and an inclination of 3° with respect to the ecliptic. [1] Chimay was first identified as A917 BB at Heidelberg in 1917, extending the body's observation arc by 12 years prior to its official discovery observation. [13]

    Physical characteristics

    Several rotational lightcurves were obtained from photometric observations. Lightcurve analysis gave a well-defined, concurring rotation period of 6.58–6.63 hours with a brightness variation between 0.31 and 0.58 magnitude ( U=3/3-/2 ). [8] [9] [10] [11] [14]

    According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Chimay measures between 36.1 and 37.7 kilometers in diameter, and its surface has a low albedo between 0.079 and 0.089. [4] [5] [6] [7] In accordance with the space-based surveys, the Collaborative Asteroid Lightcurve Link (CALL) derives an albedo of 0.078, and calculates a diameter of 36.1 kilometers. CALL also classifies Chimay as a S-type rather than a carbonaceous C-type asteroid. [3]

    Naming

    This minor planet was named after the Belgian town Chimay, home of the discoverer, who also co-discovered Comet Arend–Roland. [2] The official naming citation was published by the Minor Planet Center on 20 February 1976 ( M.P.C. 3931). [15]
