14335 Alexosipov, provisional designation1981 RR3, is a stony Floraasteroid from the inner regions of theasteroid belt, approximately 4 kilometers in diameter. It was discovered by Soviet–Russian astronomerNikolai Chernykh at theCrimean Astrophysical Observatory in Nauchnyj, on 3 September 1981.[7] The asteroid was named after astronomerAlexandr Osipov.[2]
Alexosipov is a member of theFlora family, one of the largest groups ofstony asteroids. It orbits the Sun in theinner main-belt at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,220 days). Its orbit has aneccentricity of 0.21 and aninclination of 6° with respect to theecliptic.[1] The firstastrometric observations were already made at the discovering observatory in 1971, 10 years prior to its discovery. However, these observations were not used to extend the asteroid'sobservation arc.[7]
Alexosipov has been characterized as a commonS-type asteroid byPan-STARRS photometric survey.[6]
A rotationallightcurve ofAlexosipov was obtained from photometric observations made by American astronomerBrian Skiff in October 2011. It gave a well-definedrotation period of7.18±0.01 hours with a low brightness variation of 0.10 inmagnitude (U=3).[a] A low brightness amplitude typically indicates that the body has a nearly spheroidal shape.
According to the survey carried out by theNEOWISE mission of NASA's space-basedWide-field Infrared Survey Explorer,Alexosipov measures 4.2 kilometers in diameter and its surface has analbedo of 0.279,[4][5] while theCollaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – which derives from8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 3.9 kilometers with anabsolute magnitude of 14.2.[3]
Thisminor planet was named in memory of astronomer Alexandr Kuzmich Osipov (1920–2004), observer of artificial satellites, the Moon, planets and comets at theAstronomical Observatory of the Kyiv National University in Ukraine. He is described as a skilled teacher for many generations of students.[2] The approved naming citation was published by theMinor Planet Center on 15 December 2005 (M.P.C. 55721).[8]
