It orbits the Sun in the outer main-belt at a distance of 2.9–3.2 AU once every 5 years and 3 months (1,908 days).
[3] A rotational lightcurve of Severny was obtained by French amateur astronomer Laurent Bernasconi in March 2005.
[9] In September 2013, photometric observations in the R-band at the Palomar Transient Factory, California, gave a shorter period of 9.2481 hours with an amplitude of 0.17 magnitude (U=2).
[8] 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, Severny measures between 21.33 and 24.83 kilometers in diameter, and its surface has an albedo between 0.136 and 0.181.
[3] This minor planet was named by the discoverer in honor of Soviet astronomer Andrei Severny (1913–1987), who was the Director of the Crimean Astrophysical Observatory[2] and known for his work on solar flares and astronomical observations from artificial satellites.
