1933 Tinchen, provisional designation Template:Mp, is a Vestian asteroid from the inner regions of the asteroid belt, about 5 kilometers in diameter. 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.[1][2]
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.[3]
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 the Rheasilvia crater, 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.[4][5]Template:Efn
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.[6][7] 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.[8]
Naming
The discoverer named this minor planet after his wife, Christine Kohoutek.[1] The official Template:MoMP was published by the Minor Planet Center on 20 February 1976 (M.P.C. 3938Script error: No such module "Check for unknown parameters".).[9]
