It was discovered on 8 January 1954, by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle, Belgium, and later named for the Belgian town and provincial capital, Arlon. Classification and orbit Arlon is a member of the Flora family, a collisional family of S-type asteroids asteroids, and one of the largest populations of the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.9–2.5 AU once every 3 years and 3 months (1,188 days). Its orbit has an eccentricity of 0.13 and an inclination of 6° with respect to the ecliptic. First identified as A915 CC at Simeiz Observatory in 1915, Arlon first used observation was taken at Lowell Observatory in 1930, when it was identified as 1930 YU, extending the body's observation arc by 24 years prior to its official discovery observation. Binary system Primary A large number of rotational lightcurves of Arlon were obtained from photometric observations, giving a well-defined rotation period between 5.1477 and 5.1496 hours with a small brightness variation of 0.10 magnitude or less (also see infobox).LCDB-Prave-2011 Secondary During one of these photometric observations in 2006, the binary nature of Arlon was revealed. The discovered asteroid moon orbits its primary once every 18.2 hours, at a distance of 16 kilometers. The moon itself measures approximately 4 kilometers in diameter. 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, Arlon measures between 8.48 and 9.15 kilometers in diameter and its surface has an albedo between 0.167 and 0.315. The Collaborative Asteroid Lightcurve Link agrees with the revised WISE-results by Pravec, adopting an albedo of 0.225 and a diameter of 9.15 kilometers with an absolute magnitude of 12.43. 1717 Arlon has been observed to occult two stars, in 2021 and again in 2023. Naming This minor planet was named for the Belgian town, municipality and provincial capital, Arlon. It is located on a hill above the source of the Semois river. In ancient times, Arlon was known as Orolaunum by the Romans and served as a station on the Antoninian way linking the cities Trier with Reims. The approved naming citation was published by the Minor Planet Center on 22 September 1983 (M.P.C. 8150).
