1176 Lucidor, provisional designation1930 VE, is a carbonaceous backgroundasteroid from the central region of theasteroid belt, approximately 30 kilometers in diameter. It was discovered byEugène Delporte in 1930, who named it after a friend.
Lucidor was discovered on 15 November 1930, by Belgian astronomerEugène Delporte at theRoyal Observatory of Belgium in Uccle. On the same day, it was independently discovered byMax Wolf at theHeidelberg Observatory in Germany, and 15 days later byGrigory Neujmin atSimeiz Observatory in Crimea.[13] The body'sobservation arc begins with its identification as1927 BF at the Tokyo Astronomical Observatory (389) in January 1927, nearly 4 years prior to its official discovery observation at Uccle.[13]
Lucidor has not been grouped to any knownasteroid family. It orbits the Sun in thecentral main belt at a distance of 2.3–3.1 AU once every 4 years and 5 months (1,613 days). Its orbit has aneccentricity of 0.14 and aninclination of 7° with respect to theecliptic.[1]
In theSMASS classification,Lucidor is a carbonaceousC-type asteroid.[1]
In November 2005, two rotationallightcurves ofLucidor were independently obtained from photometric observations byBrian Warner at his Palmer Divide Observatory (716) in Colorado as well as byRené Roy at Blauvac, France (627), and Federico Manzini and Roberto Crippa at Sozzago in Italy (A12). Lightcurve analysis gave a well-definedrotation period of 4.075 and 4.0791 hours with a low brightness amplitude of 0.05 and 0.06magnitude, respectively (U=3/3).[9][10][a] A low brightness variation typically indicates that the body has aspheroidal rather than an irregular shape.
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Lucidor measures between 17.489 and 31.48 kilometers in diameter and its surface has analbedo between 0.04 and 0.159.[4][5][6][7][8]
TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.0544 and a diameter of 30.59 kilometers based on anabsolute magnitude of 11.35.[3]
Thisminor planet was named after an amateur astronomer and friend of the discoverer. "Lucidor" is a female name. Her full name has not been published. The official naming citation was mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 109).[2]
