1736 Floirac, provisional designation 1967 RA, 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. [2] [11]
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. [1]
First observed as A914 WD at Simeiz Observatory in 1914, the body's observation arc begins with its 1927-identification as 1927 RB at Heidelberg Observatory, approximately 40 years prior to its official discovery observation at Bordeaux. [11]
This asteroid has been characterized as a stony S-type asteroid by PanSTARRS ' photometric survey. [10]
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=3 ). [lower-alpha 1] [lower-alpha 2] An alternative period solution of 12.28 hours (Δmag 0.25) was found by French amateur astronomer Laurent Bernasconi in June 2006 ( U=2 ). [9]
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. [4] [5] [7] [8]
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. [3] [6]
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. [2] The official naming citation was published by the Minor Planet Center on 15 July 1968 ( M.P.C. 2883). [12]
