1736 Floirac, provisional designation Template:Mp, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 8.7 kilometer in diameter.
It was discovered on 6 September 1967, by French astronomer Guy Soulié at Bordeaux Observatory in southwestern France, who named it after the French town of Floirac.[1][2]
Classification and orbit
Floirac is a member of the Flora 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 an eccentricity of 0.17 and an inclination of 5° with respect to the ecliptic.[3]
First observed as Template:Mp at Simeiz Observatory in 1914, the body's observation arc begins with its 1927-identification as Template:Mp at Heidelberg Observatory, approximately 40 years prior to its official discovery observation at Bordeaux.[2]
Physical characteristics
This asteroid has been characterized as a stony S-type asteroid by PanSTARRSTemplate:' photometric survey.[4]
Lightcurves
In October 2007, a rotational lightcurve of Floirac was obtained from photometric observations by astronomer Petr Pravec and collaborating colleges. Lightcurve analysis gave a rotation period of 6.775 hours with a low brightness variation of 0.08 magnitude (U=3Script error: No such module "Check for unknown parameters".).Template:EfnTemplate:Efn An alternative period solution of 12.28 hours (Δmag 0.25) was found by French amateur astronomer Laurent Bernasconi in June 2006 (U=2Script error: No such module "Check for unknown parameters".).[5]
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, Floirac measures between 8.617 and 10.08 kilometers in diameter and its surface has an albedo of 0.252 and 0.302.[6][7][8][9]
The Collaborative Asteroid Lightcurve Link takes an albedo of 0.2711 and a diameter of 8.73 kilometers with an absolute magnitude of 12.4, based on Petr Pravec's revised WISE-data.[10][11]
Naming
This minor planet was named by the discoverer for Floirac, a French town in the Département Gironde, near Bordeaux, where the discovering observatory is located.[1] The official Template:MoMP was published by the Minor Planet Center on 15 July 1968 (M.P.C. 2883Script error: No such module "Check for unknown parameters".).[12]
