}}3687 Dzus, provisional designation {{mp|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.[21]

Orbit and classification

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. As no precoveries were taken, the asteroid's observation arc begins with its discovery observation in 1908.[21]

Physical characteristics

The C-type asteroid is characterized as a Ch subtype in the SMASS classification.

Diameter and albedo

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.[4][5][6][7] 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.[14]

Rotation period

A fragmentary lightcurve of Dzus was obtained from photometric observations made by Robert Stephens at the Santana Observatory ({{small|646}}) in Rancho Cucamonga, California, during April to June 2002. It showed a rotation period of {{val|7.44|0.01}} hours with a brightness variation of {{val|0.25|0.04}} in magnitude during each rotation ({{small|U=1}}).[8]

Naming

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 ({{small|M.P.C. 14029}}).[32]
