22-626: A risk of impacting Earth in the few weeks following their discovery (see Potentially hazardous objects and § Videos ) . The Minor Planet Center was set up at the University of Cincinnati in 1947, under the direction of Paul Herget . Upon Herget's retirement on June 30, 1978, the MPC was moved to the Smithsonian Astrophysical Observatory, under the direction of Brian G. Marsden . From 2006 to 2015,
33-828: The Minor Planet Circulars . Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory , which is part of the Center for Astrophysics along with the Harvard College Observatory . The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as
44-811: The ecliptic . As no precoveries were taken, the asteroid's observation arc begins with its discovery observation in 1908. The C-type asteroid is characterized as a Ch subtype in the SMASS classification . 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. The Collaborative Asteroid Lightcurve Link agrees with

A key function of the MPC is helping observers coordinate follow up observations of possible near-Earth objects (NEOs) via its NEO web form and blog, the Near-Earth Object Confirmation Page . The MPC is also responsible for identifying, and alerting to, new NEOs with
66-834: The MPC. The MPC periodically releases astrometric observations of minor planets, as well as of comets and natural satellites . These publications are the Minor Planet Circulars (MPCs), the Minor Planet Electronic Circulars (MPECs), and the Minor Planet Supplements (MPSs and MPOs). An extensive archive of publications in a PDF format is available at the Minor Planet Center's website. The archive's oldest publication dates back to 1 November 1977 (MPC 4937–5016).

77-469: 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. 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
88-459: The director of the MPC was Timothy Spahr , who oversaw a staff of five. From 2015 to 2021, the Minor Planet Center was headed by interim director Matthew Holman . Under his leadership, the MPC experienced a significant period of reorganization and growth, doubling both its staff size and the volume of observations processed per year. Upon Holman's resignation on February 9, 2021 (announced on February 19, 2021) Matthew Payne became acting director of

110-642: 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. 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 ). This minor planet
121-643: 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. The official naming citation was published by the MPC on 23 December 1988 ( M.P.C. 14029 ).
