1736 Floirac, provisional designation 1967 RA, is a stony asteroid from the inner regions of the asteroid belt, about 9 kilometer in diameter. It was discovered by French astronomer Guy Soulié at Bordeaux Observatory on 6 September 1967.[9]
The stony asteroid 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 (1,216 days). Its orbit shows an eccentricity of 0.17 and is tilted by 5 degrees to the plane of the ecliptic. It has a rotation period of 6.8 hours[6] and an albedo in the range of 0.25–0.30, based on several different observations.[4][5][6][7]
The minor planet was named by the discoverer for Floirac, a French town in the Département Gironde, near Bordeaux, where the discovering observatory is located.[2]
