3687 Dzus, provisional designation A908 TC, is a carbonaceous asteroid from the central region of the asteroid belt, approximately 31 kilometers in diameter. It was discovered by German astronomer August Kopff at Heidelberg-Königstuhl State Observatory on 7 October 1908. [10]
Dzus orbits the Sun in the central main-belt at a distance of 2.2–3.3 AU once every 4 years and 6 months (1,645 days). Its orbit has an eccentricity of 0.20 and an inclination of 16 ° with respect to the ecliptic. [1] As no precoveries were taken, the asteroid's observation arc begins with its discovery observation in 1908. [10]
The C-type asteroid is characterized as a Ch subtype in the SMASS classification. [1]
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Dzus measures between 28.6 and 34.5 kilometers in diameter and its surface has an albedo between 0.038 and 0.054. [3] [4] [5] [6] The Collaborative Asteroid Lightcurve Link agrees with the results obtained by IRAS; that is an albedo of 0.038 and a diameter of 28.6 kilometers, based on an absolute magnitude of 11.5. [8]
A fragmentary lightcurve of Dzus was obtained from photometric observations made by Robert Stephens at the Santana Observatory ( 646) in Rancho Cucamonga, California, during April to June 2002. It showed a rotation period of 7.44±0.01 hours with a brightness variation of 0.25±0.04 in magnitude during each rotation ( U=1). [7]
This minor planet was named by Brian Geoffrey Marsden, long-time director of the Minor Planet Center (MPC), in honor of Paul K. Dzus (b. 1969) in appreciation of his helpful assistance since October 1987, much of the time as a volunteer. [2] The official naming citation was published by the MPC on 23 December 1988 ( M.P.C. 14029). [11]
