1379 Lomonosowa (prov. designation:1936 FC) is a stonybackground asteroid from the central regions of theasteroid belt, approximately 19 kilometers (12 miles) in diameter. Discovered byGrigory Neujmin at theSimeiz Observatory in 1936, the asteroid was later named after Russian physicist and astronomerMikhail Lomonosov.[2][15]
Lomonosowa was discovered on 19 March 1936, by Soviet astronomerGrigory Neujmin at theSimeiz Observatory on the Crimean peninsula.[15] On the same night, it was independently discovered by Serbian astronomerPetar Đurković atUccle Observatory in Belgium.[2] TheMinor Planet Center only recognizes the first discoverer.[15] A firstprecovery ofLomonosowa was taken at theLowell Observatory in October 1905. The asteroid was first identified as1933 SG1 atHeidelberg Observatory in September 1933.[15]
Lomonosowa is a non-family asteroid of the main belt'sbackground population.[3] It orbits the Sun in thecentral asteroid belt at a distance of 2.3–2.8 AU once every 4.01 years (1,464 days). Its orbit has aneccentricity of 0.09 and aninclination of 16° with respect to theecliptic.[1] The body'sobservation arc begins with its first precovery at Lowell Observatory in October 1905.[15]
Thisminor planet was named after Russian physicist and astronomerMikhail Lomonosov (1711–1765). He discovered theatmosphere of Venus and theprinciple of mass conservation.[2] The officialnaming citation was published by theMinor Planet Center in June 1955 (M.P.C. 1252).[16] He is also honored by the cratersLomonosov on the Moon andLomonosov on Mars.[2]
Lomonosowa has been characterized as a common, stonyS-type asteroid.[13]
Several rotationallightcurve ofLomonosowa have been obtained from photometric observations since the 1980s. Lightcurve analysis gave arotation period between 24.482 and 24.71 hours with a brightness amplitude of 0.45 to 0.63magnitude (U=2/3/2).[9][12][13] The asteroid's lightcurve has also been modeled using photometric observations from various sources. Modelling gave a concurring sidereal period of 24.4845 and 24.4846 hours.[10][11] One study also found two spin axis of (72.0°, −84.0°) and (265.0°, −46.0°) inecliptic coordinates (λ, β).[11]
According to the surveys carried out by the JapaneseAkari satellite and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Lomonosowa measures between 18.690 and 20.45 kilometers in diameter and its surface has analbedo between 0.1584 and 0.218.[5][6][7][8] TheCollaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 17.82 kilometers based on anabsolute magnitude of 11.11.[4]
