1115 Sabauda/səˈbɔːdə/ is a carbonaceous Meliboeanasteroid from the outer region of theasteroid belt, approximately 68 kilometers in diameter. Discovered in 1928 by Italian astronomerLuigi Volta, it was assigned the provisional designation1928 XC. The asteroid was probably named after theHouse of Savoy, the former rulers of Italy.[2][13]
Sabauda was discovered on 13 December 1928, by Italian astronomerLuigi Volta at theObservatory of Turin (Pino Torinese Observatory).[13] Five nights later, it was independently discovered by Catalan astronomerJosep Comas i Solà at theFabra Observatory in Barcelona, Spain. The asteroid was first identified asA906 YF atHeidelberg Observatory in December 1906,[2] and itsobservation arc begins at Heidelberg in January 1929, one month after its official discovery observation at Pino Torinese.[13]
Sabauda is a member of theMeliboea family, a smallerasteroid family of carbonaceous outer-belt asteroids with a few hundred members, named after137 Meliboea.[4][14]: 23 It orbits the Sun in theouter main-belt at a distance of 2.6–3.6 AU once every 5 years and 6 months (1,998 days). Its orbit has aneccentricity of 0.17 and aninclination of 15° with respect to theecliptic.[1]
Sabauda is an assumed carbonaceousC-type asteroid,[3] in line with the Meliboea family's overallspectral type.[14]: 23
Several rotationallightcurves ofSabauda were obtained from photometric observations. Lightcurve analysis gave arotation period between 6.718 and 6.732 hours with a brightness amplitude of 0.16 to 0.27magnitude (U=2+/3-/3).[9][10][11][a][b]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Sabauda measures between 67.24 and 75.91 kilometers in diameter and its surface has analbedo between 0.04 and 0.0711.[5][6][7][8]
TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.0496 and a diameter of 68.53 kilometers based on anabsolute magnitude of 9.7.[3]
Thisminor planet bears the Latin name of the former rulers of Italy, theHouse of Savoy (Sabauda, or Sapauda). It is also possible that it was named after the new established town of Sabauda in thePontine Marshes, central Italy.[2] The official naming citation was mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 104).[2]
