Its name comes from the ancient Latin name for the Garonne River in France. This object is orbiting the Sun at a distance of 2.72 AU with an eccentricity of 0.165 and an orbital period of 4.49 years. The orbital plane is inclined at an angle of 0.87° to the plane of the ecliptic. Based on infrared observations, this object has a diameter of 23.4 km. In the Tholen classification system, it is categorized as a stony S-type asteroid, while the Bus asteroid taxonomy system lists it with the Sr sub-type. The rotation period of this asteroid is very nearly equal to that of the rotation of the Earth. This means that only a small portion of the light curve can be observed from any one location, requiring measurements from multiple sites in order to build a complete curve. In 2012, this mission was accomplished, giving a period of 23.8660.001 hours with a brightness variation of 0.420.02 in magnitude. Allowing for a margin of error and changes in phase angle, this finding agrees with previous measurements made in 2008 and 2011.
