It was discovered on 14 January 1972, by Czech astronomer Luboš Kohoutek at the Hamburger Bergedorf Observatory in Germany, who named it after his wife, Christine Kohoutek. Classification and orbit Tinchen orbits the Sun in the inner main-belt at a distance of 2.1–2.6 AU once every 3 years and 7 months (1,318 days). Its orbit has an eccentricity of 0.12 and an inclination of 7° with respect to the ecliptic. The vestoid or V-type asteroid is also a member of the Vesta family. Asteroids with these spectral and orbital characteristics are thought to have all originated from Rheasilvia, a large impact crater on the south-polar surface of 4 Vesta, which is the main-belt's second-most-massive asteroid after 1 Ceres. Physical characteristics Tinchen has a rotation period of 3.671 hours.LCDB-Ryan-2007 According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Tinchen measures between 4.51 and 6.454 kilometers in diameter and its surface has an albedo between 0.2950 and 0.613. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for Vestian asteroids of 0.40 and calculates a diameter of 5.04 kilometers with an absolute magnitude of 13.1. Naming The discoverer named this minor planet after his wife, Christine Kohoutek. The official 1933 naming citation was published by the Minor Planet Center on 20 February 1976 (M.P.C. 3938).
