The asteroid was discovered on 27 January 1993, by Belgian astronomer Eric Elst at Caussols (010) in southeastern France. It was later named after the Russian city of Arzamas. Orbit and classification Arzamas is a member of the Themis family, a dynamical family of outer main-belt asteroids with nearly co-planar ecliptical orbits. It orbits the Sun in the outer main-belt at a distance of 2.7–3.7 AU once every 5 years and 9 months (2,095 days). Its orbit has an eccentricity of 0.15 and an inclination of 1° with respect to the ecliptic. The body's observation arc begins 22 years prior to its official discovery observation, when it was identified as 2118 T-1 at Palomar Observatory during the first Palomar–Leiden Trojan survey in 1971. Physical characteristics Lightcurves In February 2010, two rotational lightcurves of Arzamas were obtained from photometric observations at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 12.1 and 12.1991 hours with a brightness variation of 0.7 and 0.6 magnitude, respectively (U=2/2). Diameter and albedo According to the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Arzamas measures 10.8 kilometer in diameter, and its surface has an albedo of 0.08. The Collaborative Asteroid Lightcurve Link also assumes an albedo of 0.08, characterizes it as a C-type asteroid, and calculates a diameter of 10.3 kilometers with an absolute magnitude of 13.4. Naming This minor planet was named after the Russian city of Arzamas, a major transit center on the road from Moscow to the eastern parts of the country. It was founded in 1578 by Ivan the Terrible and is located on the Tyosha River, known for making leather and dyeing fabrics ever since. The official naming citation was published by the Minor Planet Center on 24 November 2007 (M.P.C. 61266). References 30em 2017-05-05 last obs.
