1736 Floirac

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.

First observed as {{mp|A914 WD}} at Simeiz Observatory in 1914, the body's observation arc begins with its 1927-identification as {{mp|1927 RB}} at Heidelberg Observatory, approximately 40 years prior to its official discovery observation at Bordeaux.

This asteroid has been characterized as a stony S-type asteroid by PanSTARRS{{'}} photometric survey.

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 ({{small|U=3}}).{{efn|name=LCDB-Pravec-2007}}{{efn|name=lightcurve-plot}} An alternative period solution of 12.28 hours (Δmag 0.25) was found by French amateur astronomer Laurent Bernasconi in June 2006 ({{small|U=2}}).

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.

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.

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. The official {{MoMP|1736|naming citation}} was published by the Minor Planet Center on 15 July 1968 ({{small|M.P.C. 2883}}).
