1736 Floirac, provisional designation1967 RA, is a stony Florianasteroid from the inner regions of theasteroid belt, approximately 8.7 kilometer in diameter.
It was discovered on 6 September 1967, by French astronomerGuy Soulié atBordeaux Observatory in southwestern France, who named it after the French town ofFloirac.[2][11]
Floirac is a member of theFlora family. It orbits the Sun at a distance of 1.9–2.6 AU once every 3 years and 4 months (1,215 days). Its orbit has aneccentricity of 0.17 and aninclination of 5° with respect to theecliptic.[1]
First observed asA914 WD atSimeiz Observatory in 1914, the body'sobservation arc begins with its 1927-identification as1927 RB atHeidelberg Observatory, approximately 40 years prior to its official discovery observation at Bordeaux.[11]
This asteroid has been characterized as a stonyS-type asteroid byPanSTARRS' photometric survey.[10]
In October 2007, a rotationallightcurve ofFloirac was obtained from photometric observations by astronomerPetr Pravec and collaborating colleges. Lightcurve analysis gave arotation period of 6.775 hours with a low brightness variation of 0.08magnitude (U=3).[a][b] An alternative period solution of 12.28 hours (Δmag 0.25) was found by French amateur astronomerLaurent Bernasconi in June 2006 (U=2).[9]
According to the surveys carried out by the JapaneseAkari satellite and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Floirac measures between 8.617 and 10.08 kilometers in diameter and its surface has analbedo of 0.252 and 0.302.[4][5][7][8]
TheCollaborative Asteroid Lightcurve Link takes an albedo of 0.2711 and a diameter of 8.73 kilometers with anabsolute magnitude of 12.4, based onPetr Pravec's revised WISE-data.[3][6]
Thisminor planet was named by the discoverer forFloirac, a French town in the Département Gironde, near Bordeaux, where the discovering observatory is located.[2] The officialnaming citation was published by theMinor Planet Center on 15 July 1968 (M.P.C. 2883).[12]
