[3][12] In October 1984, a rotational lightcurve of Volga was obtained from photometric observations by American astronomer Richard Binzel.
Lightcurve analysis gave a somewhat longer-than average rotation period of 27.5 hours with a brightness amplitude of 0.26 magnitude (U=2).
[11] According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's WISE telescope, Volga measures between 48.50 and 57.67 kilometers in diameter and its surface has an albedo between 0.03 and 0.04.
[5][6][7][8][9][10] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0338 and a diameter of 55.57 kilometers based on an absolute magnitude of 10.57.
