It was discovered on 18 August 1933, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle, Belgium. It was later named after astronomer Georges Roland's sister-in-law. Orbit and classification Delvaux is a stony asteroid and a member of the Koronis family, a collisional group consisting of a few hundred known bodies with nearly ecliptical orbits. It orbits the Sun in the outer main-belt at a distance of 2.7–3.0 AU once every 4 years and 10 months (1,777 days). Its orbit has an eccentricity of 0.05 and an inclination of 1° with respect to the ecliptic. First identified as A912 FA at Simeiz Observatory in 1912, the body's observation arc begins 3 day after its official discovery, as non of the previous observations were used. Physical characteristics In the SMASS taxonomy, Delvaux is a common S-type asteroid. Rotation period It has a well-determined rotation period of 3.63 to 3.65 hours with a brightness variation of 0.57–0.69 magnitude (U=3/3/3/3). The Collaborative Asteroid Lightcurve Link (CALL) adopts a period of 3.637 hours. Diameter and albedo According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Delvaux measures between 16.66 and 17.51 kilometers in diameter, and its surface has an albedo of 0.233 to 0.461. CALL assumes a standard albedo for members of the Koronis family of 0.24, and calculates a diameter of 17.12 kilometers with an absolute magnitude of 11.0. Name This minor planet was named after the sister-in-law of Georges Roland, astronomer at the observatory in Uccle and known as the co-discoverer of the comet Arend–Roland. The approved naming citation was published by the Minor Planet Center on 8 April 1982 (M.P.C. 6832). References 2017-02-04 last obs.
