1967 Menzel, provisional designation A905 VC, is a stony asteroid from the inner regions of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 1 November 1905, by German astronomer Max Wolf at Heidelberg Observatory in southern Germany, and later named after American astrophysicist Donald Howard Menzel.
Menzel is a stony S-type asteroid that orbits the Sun in the inner main-belt at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,220 days). Its orbit has an eccentricity of 0.14 and an inclination of 4° with respect to the ecliptic. The body's observation arc begins with its first used observation at Goethe Link Observatory in 1965, or 60 years after its official discovery, with a number of unused observations previously made at Heidelberg.
Between September 2005 and November 2015, a total of least 10 rotational lightcurves were obtained for this asteroid from photometric observations from several observatories all over the world. They all gave a concurring, well-defined rotation period of 2.83–2.84 hours with a brightness variation between 0.24 and 0.39 magnitude.(U=3/3/3/3/3/3/3/3/2+/3).
According to the space-based survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Menzel measures between 9.6 and 10.2 kilometers in diameter and its surface has an albedo between 0.21 and 0.25. The Collaborative Asteroid Lightcurve Link derives a typical albedo for stony asteroids of 0.21 and a diameter of 10.1 kilometers, with an absolute magnitude of 12.25.
