9549 Akplatonov
9549 Akplatonov, provisional designation 1985 SM2, is a stony asteroid from the middle region of the asteroid belt, about 9 kilometers in diameter. It was discovered by the couple of Soviet–Russian astronomers, Nikolai and Lyudmila Chernykh, at the Crimean Astrophysical Observatory in Nauchnyj, Crimea, on 19 September 1985. The asteroid is a member of the Eunomia family, a large group of stony S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.3–2.9 AU once every 4 years and 3 months (1,537 days). Its orbit shows an eccentricity of 0.11 and is tilted by 11 degrees to the plane of the ecliptic. The asteroid's rotation period amounts to 2.8 and 4.7 hours, determined by two divergent observations made in 2009 and 2011. According to the survey carried out by the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the body has an albedo of 0.29, while the Collaborative Asteroid Lightcurve Link assumes a somewhat more moderate albedo of 0.21. The minor planet was named after Russian computational mathematician, Aleksandr Konstantinovich Platonov (b. 1931), researcher in orbital mechanics and robotics at the Keldysh Institute of Applied Mathematics since 1954. He is a pioneer in the theory and computation of satellite orbits and the control of spacecraft trajectories to the Moon and planets, as well as the motion of walking robots.
