1927 Suvanto, provisional designation1936 FP, is a stony Eunomianasteroid from the central region of theasteroid belt, approximately 12 kilometers in diameter. It was discovered on 18 March 1936, by Finnish astronomerRafael Suvanto at theTurku Observatory in Southwest Finland.[10] The asteroid was posthumously named in honor of the discoverer.[2]
Suvanto is a member of theEunomia family, the most prominent family in the intermediate main-belt, which mostly consists of stonyS-type asteroids. It orbits the Sun at a distance of 2.3–3.0 AU once every 4 years and 4 months (1,577 days). Its orbit has aneccentricity of 0.15 and aninclination of 13° with respect to theecliptic.[1]
It will pass 0.048 AU (7,200,000 km) from2 Pallas on 24 May 2074, which will allow a refinement to the known mass of Pallas.[1]
Photometric observations ofSuvanto collected during 2004–2005 show arotation period of8.163 hours with a brightness variation of0.60magnitude.[7]
Thisminor planet was named in memory ofRafael Suvanto (credited discoverer), assistant ofYrjö Väisälä. Suvanto died during the last days of the Finnish Winter War of in theBattle of Summa(also see naming of asteroid1928 Summa).[2] The approved naming citation was published by theMinor Planet Center on 1 August 1980 (M.P.C. 5450).[11]
