It was discovered by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland, on 20 January 1939.The vestoid or V-type asteroid is a member of the Vesta family. It orbits the Sun at a distance of 2.2–2.5 AU once every 3 years and 8 months (1,327 days). Its orbit shows an eccentricity of 0.08 and an inclination of 8 degrees from the plane of the ecliptic. Vestian asteroids have a composition akin to cumulate eucrite meteorites and are thought to have originated deep within 4 Vesta's crust, possibly from the Rheasilvia crater, a large impact crater on its southern hemisphere near the South pole, formed as a result of a subcatastrophic collision. The asteroid Vesta is the main-belt's second-most-massive body after 1 Ceres.The asteroid has a well-defined rotation period of 2.98 hours, determined by two photometric light-curve analysis. The first observation in 2004, at the U.S. Magdalena Ridge Observatory in New Mexico rendered a period of 7000298000000000000♠2.980±0.005 hours, with a brightness amplitude of 0.20 in magnitude. In 2008 a second, concurring observation by French amateur astronomer Pierre Antonini at his private Observatoire de Bédoin (132) in France, gave a period of 7000298870000000000♠2.9887±0.0004 hours and a corresponding amplitude 0.22 mag.According to the surveys carried out by NASA's Wide-field Infrared Survey Explorer and its subsequent NEOWISE mission, the body measures 6.7 and 7.7 kilometers in diameter, respectively, and its surface has an albedo 0.39. The Collaborative Asteroid Lightcurve Link assumes an almost identical albedo of 0.40, yet calculates a somewhat shorter diameter of 6.4 kilometers.The minor planet is named after the Kollaa River in Karelia, the focal point of the of violent battles during the Finnish Winter War (1939–40)."@en }
