Campai is a member of the Witt family (535), a large family of (predominantly) stony asteroids with more than 1,600 known members. It orbits the Sun in the central main-belt at a distance of 2.7-2.8 AU once every 4 years and 7 months (1,673 days; semi-major axis of 2.76 AU). Its orbit has an eccentricity of 0.02 and an inclination of 7° with respect to the ecliptic. The first precovery was obtained at Siding Spring Observatory in July 1977, extending the asteroid's observation arc by 22 years prior to its discovery.
