Setvák is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.9-2.8 AU once every 3 years and 7 months (1,315 days). Its orbit has an eccentricity of 0.18 and an inclination of 3° with respect to the ecliptic. Its observation arc dates back to 1979, due to precoveries obtained at the U.S. Palomar Observatory and the Siding Spring Observatory in Australia.
