It was discovered on 31 August 1929, by Soviet astronomer Grigory Neujmin at Simeiz Observatory on the Crimean peninsula.
[13] Based on its orbital elements, Luda is a member of the Eunomia family, a large group of stony asteroids and the most prominent family in the intermediate main-belt, while Argentine astronomer Alvarez-Candal from the Universidad Nacional de Córdoba groups it into the smaller Maria family, which is named after 170 Maria (the same discrepancy exists for 9175 Graun and 2429 Schürer).
[9][10][11] Photometric observations also gave a period of 6.9 and 7.44 hours, but these were derived from a fragmentary and ambiguous light curve, respectively.(U=1/2).
[3][12] According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Luda measures between 18.63 and 20.59 kilometers in diameter and its surface has an albedo between 0.20 and 0.25.
[5][6][7][8] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.232 and a diameter of 19.06 kilometers with an absolute magnitude of 10.8.
