It orbits the Sun in the central main-belt at a distance of 2.1–3.1 AU once every 4 years and 3 months (1,548 days).

[11] From 2007 to 2012, several photometric lightcurve observations of Yugoslavia established a well-defined rotation period of 3.89 hours with a brightness variation between 0.64 and 0.74 magnitude (U=3/3/3).

[8][9][10] According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Yugoslavia measures between 14.73 and 21.39 kilometers in diameter, and its surface has an albedo between 0.070 and 0.269.

[4][5][6][7] 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 15.94 kilometers with an absolute magnitude of 11.3.
