    1967 Menzel, provisional designation A905 VC, is a stony asteroid from the inner regions of the asteroid belt, about 10 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg Observatory in southern Germany, on 1 November 1905.[12]

    The S-type asteroid orbits the Sun at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,219 days). Its orbit shows an eccentricity of 0.14 and is tilted by 4 degrees to the plane of the ecliptic. A large number of photometric light-curve analysis between 2005 and 2015 have rendered a concurring, well-defined period of 2.84 hours for the body's rotation around its own axis (see adjunct infobox). It has an albedo of 0.21–0.23, according to the survey carried out by the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission.[4][5]

    It was named after American astronomer Donald Howard Menzel (1901–1976), who was the director of the Harvard College Observatory. He was both, a theoretical and observational pioneering solar and stellar astrophysicist. Menzel calculated atomic transition probabilities, analysed the composition of stars and nebulae. He also made fundamental contributions to the understanding of physical processes in gaseous nebulae, the solar chromosphere, and interpretation of stellar spectra. He observed 15 solar eclipses, determined spectroscopically the rotation rates of Uranus and Neptune and helped educate a number of prominent astronomers. On the lighter side, Menzel is well known for his doodling and for debunking of UFO's.[2]
