1436 Salonta, provisional designation1936 YA, is a dark backgroundasteroid from the outer regions of theasteroid belt, approximately 60 kilometers in diameter. Discovered byGyörgy Kulin at theKonkoly Observatory in 1936, the asteroid was later named for the Romanian city ofSalonta, the birthplace of the discoverer.
Salonta was discovered on 11 December 1936, by Hungarian astronomerGyörgy Kulin at theKonkoly Observatory in Budapest.[15] Three nights later, it was independently discovered by French astronomerAndré Patry atNice Observatory on 14 December 1936.[2] TheMinor Planet Center only recognizes the first discoverer.[15] The asteroid was first identified as1933 FX1 atJohannesburg Observatory in March 1933.[15]
Salonta is a non-family asteroid from the main belt'sbackground population.[4] It orbits the Sun in theouter asteroid belt at a distance of 3.0–3.3 AU once every 5 years and 7 months (2,038 days). Its orbit has aneccentricity of 0.06 and aninclination of 14° with respect to theecliptic.[1] The body'sobservation arc begins at the discovering Konkloy Observatory in January 1937, about one month after its official discovery observation.[15]
Salonta has been characterized as a dark and primitiveP-type asteroid by theWide-field Infrared Survey Explorer (WISE).[9] It is also an assumed carbonaceousC-type asteroid.[3]
In 2007 and 2008, three rotationallightcurves ofSalonta were independently obtained from photometric observations by astronomersBrian Warner,Pierre Antonini andRené Roy. Lightcurve analysis gave a well definedrotation period between 8.861 and 8.8716 hours with a brightness amplitude of 0.17 to 0.33magnitude (U=3/3/3).[12][13][a]
In 2016, a lightcurve ofSalonta has also been modeled using data from the Uppsala Asteroid Photometric Catalogue, thePalomar Transient Factory survey, and from individual observers. Modelling gave a concurring sidereal period of 8.86985 hours as well as two spin axis of (223.0°, 18.0°) and (57.0°, 35°) inecliptic coordinates (λ, β).[16]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite and theNEOWISE mission of NASA's WISE telescope,Salonta measures between 52.73 and 72.06 kilometers in diameter and its surface has analbedo between 0.028 and 0.05.[5][6][7][8][9][10][11]
TheCollaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0339 and a diameter of 62.90 kilometers based on anabsolute magnitude of 10.3.[3]
Thisminor planet was named after the Romanian city ofSalonta, formerly known as "Nagyszalonta" when it was still part of theKingdom of Hungary. It is the birthplace of the discovererGyörgy Kulin.[2] The officialnaming citation was published by theMinor Planet Center on 1 February 1980 (M.P.C. 5182).[17]
