1460 Haltia, provisional designation1937 WC, is a stony backgroundasteroid from the central regions of theasteroid belt, approximately 8 kilometers in diameter. It was discovered on 24 November 1937, by Finnish astronomerYrjö Väisälä at theIso-Heikkilä Observatory in Turku, Finland.[10] The asteroid was named afterHalti (Haltia), Finland's highest peak on the border to Norway.[2]
Haltia is a non-family asteroid of the main belt'sbackground population.[3] It orbits the Sun in thecentral asteroid belt at a distance of 2.1–3.0 AU once every 4 years and 1 month (1,481 days). Its orbit has aneccentricity of 0.19 and aninclination of 7° with respect to theecliptic.[1] The body'sobservation arc begins with its official discovery observation at Turku.[10]
Haltia is an assumed stonyS-type asteroid.[7]
Two rotationallightcurves ofHaltia were obtained from photometric observations by astronomers Henk de Groot,Raoul Behrend andRené Roy. Lightcurve analysis gave a respectiverotation period of 3.58682 and 3.588 hours with a brightness amplitude of 0.32magnitude (U=3-/3).[8] The Lightcurve Data Base adopts a consolidated period of 3.59 hours.[7]
According to the surveys carried out by the JapaneseAkari satellite and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Haltia measures between 6.57 and 8.44 kilometers in diameter and its surface has analbedo between 0.186 and 0.36.[4][5][6]
TheCollaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 8.97 based on anabsolute magnitude of 12.6.[7]
Thisminor planet was named afterHalti (Haltia), the highest Finnish peak at 1,365 metres (4,478 ft) located on the border between Norway and Finland.[2] The officialnaming citation was published by theMinor Planet Center on 20 February 1976 (M.P.C. 3928).[11]
