It was discovered on 25 October 1973, by Swiss astronomer Paul Wild at Zimmerwald Observatory, near Bern, Switzerland.
[2] With an diameter of 65–80 kilometers, it is one of the largest members of the Hilda group of asteroids, which are in 3:2 orbital resonance with the gas-giant Jupiter.
[4][5][6][8] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0316 and a diameter of 80.11 kilometers based on an absolute magnitude of 9.85.
[7] Two rotational lightcurves of Schubart were obtained from photometric observations by Johan Warell and Robert Stephens in 2015 and 2016, respectively.
He studied in detail members of the Hilda family, as he developed an averaging techniques for observing the long-term motions of asteroids.
