1911 Schubart, provisional designation 1973 UD, is an outer main-belt asteroid discovered on October 25, 1973, by Paul Wild at Zimmerwald Observatory, near Bern, Switzerland.[1]
With an diameter of 80 kilometers, it is one of the largest members of the Hilda family asteroids, which are in 3:2 orbital resonance with the gas-giant Jupiter. It is also the largest and name-giving body of the Schubart family, a collisional subgroup with related orbits, believed to have originated from a previously existing, larger asteroid (also see Asteroid family).[3] It is the darkest P-type asteroid with a very low geometric albedo of 0.0249.[1]
The asteroid is named in honor of German astronomer Joachim Schubart, from the Astronomisches Rechen-Institut. He developed an averaging techniques for observing the long-term motions of minor planets, which he applied to study in detail the members of the Hilda family.[2]
