It was his first asteroid discovery and was given the Latin name of his homeland. This object is orbiting the Sun at a distance of 2.29 AU with an eccentricity of 0.08 and an orbital period of 3.46 years. The orbital plane is inclined at an angle of 9.6° to the plane of the ecliptic. The cross-sectional diameter of this asteroid is 40.14 km. Based upon its spectrum, it is classified as a metallic M-type spectrum, although Clark et al. (1994) suggest it may be more like a stony S-type asteroid. It shows almost no absorption features in the near infrared, which may indicate an iron or enstatite chondrite surface composition. A weak hydration feature was detected in 2006. Photometric observations of this asteroid at the European Southern Observatory in 1981 gave a light curve with a period of 11.5 ± 0.1 hours and a brightness variation of 0.40 in magnitude. As of 2013, the estimated rotation period is 11.4969 hours. Notes References 2018-02-26 last obs.
