It was discovered by the Indiana Asteroid Program at the U.S. Goethe Link Observatory near Brooklyn, Indiana at on 28 January 1950.The dark asteroid is a member of the Themis family, a dynamical family of outer-belt asteroids with nearly coplanar ecliptical orbits. It orbits the Sun at a distance of 2.6–3.7 AU once every five and a half years (2,014 days). Its orbit shows an eccentricity of 0.18 and is tilted by 2 degrees to the plane of the ecliptic. It has a rotation period of 18 hours and an albedo between 0.05 and 0.08, based on data from the IRAS, WISE and NEOWISE surveys.It is a B-type asteroid under the Tholen classification taxonomy, a rare subtype of the abundant carbonaceous C-types found in the outer belt. The spectra of B-type bodies show a broad absorption feature at one mircon wavelength that is associated with the presence of magnetite and is what gives the asteroid its blue tint. There are only a few dozens asteroids known to display such a B-spectrum.The Themistian asteroids was named after Conrad M. Bardwell (1926–2010), a research associate at the Cincinnati Observatory and later associate director of the Minor Planet Center in Cambridge, Massachusetts, United States. Bardwell successfully established numerous identifications from observations in widely separated oppositions and provided observers with reliable data of orbital elements."@en }
