[2] When applying the hierarchical clustering method to its proper orbital elements, Vecherka has both been considered a non-family asteroid of the main belt's background population (according to Nesvorný),[4] and core member of the Maria family (according to Milani and Knežević).
[12] Vecherka is an assumed stony S-type asteroid,[9] which corresponds to the overall spectral type of the Maria family.
Lightcurve analysis gave a long rotation period of 336±48 hours with a brightness variation of 1.08 magnitude (U=2), indicating that the body's shape is irregular and elongated rather than spherical.
[5][6][7][8] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 10.06 kilometers based on an absolute magnitude of 12.3.
[9] Based on a proposal by the Institute of Theoretical Astronomy (ITA), this minor planet was named after Vechernij Petersburg, a popular evening newspaper from Saint Petersburg, Russia, that publishes astronomical information and articles popularizing astronomical knowledge on a regular basis.
