[4] Duboshin is an asteroids of the dynamical Hilda group which stay in a 3:2 orbital resonance with Jupiter.
[1][4] It is, however, not a member of the collisional Hilda family but a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
[6] In April 2016, a rotational lightcurve of Duboshin was obtained from photometric observations by Robert Stephens at the Center for Solar System Studies (U81) in California.
Lightcurve analysis gave a long rotation period of 50.78 hours with a brightness amplitude of 0.15 magnitude, indicative for a nearly spherical shape (U=2+).
[6][7][8] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0496 and a diameter of 54.94 kilometers based on an absolute magnitude of 10.18.
