[2][9] Swann orbits the Sun in the inner main-belt at a distance of 1.8–3.0 AU once every 3 years and 8 months (1,349 days).
[1] According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Swann measures 9.5 and 11.1 kilometers in diameter and its surface has an albedo of 0.029 and 0.101, respectively.
[3] In July 2006, a rotational lightcurve of Swann was obtained from photometric observations by Petr Pravec at the Ondřejov Observatory in the Czech Republic.
[a] A second lightcurve obtained by Jean-Gabriel Bosch in September 2006, gave a period of 4.1±0.1 hours and an amplitude of 0.35 magnitude (U=2).
[6] This minor planet was named after American geologist Gordon A. Swann (born 1931).
