14335 Alexosipov, provisional designation 1981 RR3, is a stony asteroid from the inner regions of the asteroid belt, about yzx kilometers in diameter. It was discovered by Soviet–Russian astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on 3 September 1981.[2]
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,220 days). Its orbit shows an eccentricity of 0.21 and is tilted by 6 degrees to the plane of the ecliptic. It has a rotation period of 7.2 hours[lower-alpha 1] and an albedo of 0.28, according to the NEOWISE mission of the Wide-field Infrared Survey Explorer, while the Collaborative Asteroid Lightcurve Link (CALL) assumes a somewhat more moderate albedo of 0.24, typical for asteroids with a stony surface composition.[3][4]
The minor planet was named in memory of Alexandr Kuzmich Osipov (1920–2004) at the Astronomical Observatory of Kyiv National University, who was a talented teacher for many generations of students. His work included observations of artificial satellites and studies of the Moon, planets and comets.[2]
