11824 Alpaidze, provisional designation 1982 SO5, is a stony asteroid from the middle region of the asteroid belt, about 5 kilometers in diameter. It was discovered on 16 September 1982, by Russian female astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[2]
The S-type asteroid orbits the Sun at a distance of 1.8–3.4 AU once every 4 years and 3 months (1,563 days). Its orbit shows an eccentricity of 0.31 and is tilted by 2 degrees to the plane of the ecliptic. It has a rotation period of 4.1 hours.[4] The Collaborative Asteroid Lightcurve Link assumes a low albedo of 0.10, which is rather untypical for a stony asteroid.[3]
The minor planet is named after Georgian-born, Soviet Lieutenant General Galaktion Alpaidze (1916–2006), Hero of the Soviet Union and laureate of the USSR State Prize, who was the chief of the cosmodrome in Plesetsk from 1963 to 1975. Under his leadership the cosmodrome was developed for testing space vehicles, and it became the most active launch site in the world.[2]
