Lucidor was discovered on 15 November 1930, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle.
It orbits the Sun in the central main belt at a distance of 2.3–3.1 AU once every 4 years and 5 months (1,613 days).
[1] In November 2005, two rotational lightcurves of Lucidor were independently obtained from photometric observations by Brian Warner at his Palmer Divide Observatory (716) in Colorado as well as by René Roy at Blauvac, France (627), and Federico Manzini and Roberto Crippa at Sozzago in Italy (A12).
Lightcurve analysis gave a well-defined rotation period of 4.075 and 4.0791 hours with a low brightness amplitude of 0.05 and 0.06 magnitude, respectively (U=3/3).
[4][5][6][7][8] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0544 and a diameter of 30.59 kilometers based on an absolute magnitude of 11.35.
