Gaussia (minor planet designation: 1001 Gaussia), provisional designation 1923 OA, is a dark background asteroid from the outer regions of the asteroid belt, approximately 73 kilometers in diameter. It was discovered on 8 August 1923, by Soviet astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula.[15] The asteroid was named after German mathematician Carl Friedrich Gauss.[3] Gauss computed the orbit of Ceres, and 1001 Gaussia was named along with 1000 Piazzia, and 1002 Olbersia in part for their work on Ceres, with names for Giuseppe Piazzi, who found Ceres, and Heinrich Wilhelm Matthias Olbers, who recovered it later that year.[16]
