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]

Orbit and classification

Gaussia is a background asteroid that does not belong to any known asteroid family. It orbits the Sun in the outer main-belt at a distance of 2.8–3.6 AU once every 5 years and 9 months (2,100 days). Its orbit has an eccentricity of 0.13 and an inclination of 9° with respect to the ecliptic.[1]

The asteroid was first identified as A907 XC at Taunton Observatory (

803) in December 1907. The body's observation arc begins at UNSO in January 1908, more than 15 years prior to its official discovery observation at Simeiz.[15]

Lower-rated lightcurves with a divergent period of 4.08 and 9.17 hours were previously obtained in 2005 and 2009, respectively (

U=1/2-).[12][13]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.036 and 0.05.[5][6][7][8][9][10][11]

The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0417 and a diameter of 74.71 kilometers based on an absolute magnitude of 9.7.[4]

Naming

528), who also rediscovered Ceres using a new orbital computing method by Franz Xaver von Zach.[3]

The official naming citation was mentioned in

1001 Gaussia was named as part of trio honoring the events surrounding the discovery of Ceres in 1801.[17] Carl Friedrich Gauss who computed the orbit of Ceres was for 1001 Gaussia, 1000 Piazzia for Giuseppe Piazzi and 1002 Olbersia for Heinrich Wilhelm Matthias Olbers.[17] Olbers recovered Ceres after it has passed behind the Sun and returned.[17] In the next few years only three more astronomical bodies were found between Mars and Jupiter, Pallas, Juno, and 4 Vesta, however it would be 37 years before another asteroid was found, 5 Astraea in 1845.[17]
