Lomonosowa is a non-family asteroid of the main belt's background population.[3] It orbits the Sun in the central asteroid belt at a distance of 2.3–2.8 AU once every 4.01 years (1,464 days). Its orbit has an eccentricity of 0.09 and an inclination of 16° with respect to the ecliptic.[1] The body's observation arc begins with its first precovery at Lowell Observatory in October 1905.[15]
Several rotational lightcurve of Lomonosowa have been obtained from photometric observations since the 1980s. Lightcurve analysis gave a rotation period between 24.482 and 24.71 hours with a brightness amplitude of 0.45 to 0.63 magnitude (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°) in ecliptic coordinates (λ, β).[11]
Diameter and albedo
According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Lomonosowa measures between 18.690 and 20.45 kilometers in diameter and its surface has an albedo between 0.1584 and 0.218.[5][6][7][8] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 17.82 kilometers based on an absolute magnitude of 11.11.[4]
