    1887 Virton, provisional designation 1950 TD, is a stony Eoan asteroid from the outer region of the asteroid belt, approximately 21 kilometers in diameter. It was discovered by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle on 5 October 1950, and named after the Belgian town of Virton. [2] [7]

    Orbit and classification

    Virton is a member of the Eos family. It orbits the Sun in the outer main-belt at a distance of 2.7–3.3  AU once every 5 years and 3 months (1,902 days). Its orbit has an eccentricity of 0.11 and an inclination of 10° with respect to the ecliptic. [1]

    The body's observation arc begins with its official discovery observation at Uccle, as previous observations at Johannesburg, Crimea-Simeis and Turku Observatory remained unused. [7]

    Physical characteristics

    The asteroid has been characterized as a common stony S-type asteroid. [3]

    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, Virton measures between 20.8 and 23.43 kilometers in diameter and its surface has an albedo between 0.105 and 0.124, respectively. [4] [5] [6] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.14 and calculates a diameter of 21.4 kilometers with an absolute magnitude of 11.1. [3]

    Lightcurves

    As of 2017, Virton's rotation period and shape remain unknown. [1] [3]

    Naming

    This minor planet was named after the town and capital district, Virton, in the southernmost part Belgium. It is located very close to Robelmont, Arend's birthplace (also see 1145 Robelmonte). [2] The official naming citation was published by the Minor Planet Center on 22 September 1983 ( M.P.C. 8151). [8]
