It was named after a fictional character in the Greek legend of Baucis and Philemon. The adjectival form of the name is Baucidian. This object is orbiting the Sun at a distance of 2.38 AU with an eccentricity of 0.11 and an orbital period of 3.67 years. The orbital plane is inclined at an angle of 10° to the plane of the ecliptic. Based on infrared measurements, it has a diameter of 62.43 km. It is classified as an S-type asteroid based upon its spectrum. Photometric observations of this asteroid from the southern hemisphere during 2003 gave a light curve that indicated a slow synodic rotation period of 27.417 ± 0.013 hours and a brightness variation of 0.25 in magnitude. Polarimetric study of this asteroid reveals anomalous properties that suggests the regolith consists of a mixture of low and high albedo material. This may have been caused by fragmentation of an asteroid substrate with the spectral properties of CO3/CV3 carbonaceous chondrites. References Donald K.
