1390 Abastumani, provisional designation 1935 TA, is a large, rare-type asteroid from the outer region of the asteroid belt, about 102 kilometers in diameter. It was discovered on 3 October 1935, by Soviet–Russian female astronomer Pelageya Shajn at Simeiz Observatory on the Crimean peninsula.[8] On the same night, the asteroid was independently discovered by South African astronomer Cyril Jackson at Johannesburg Observatory.[2] It was one of the last large-sized bodies discovered in the outer belt (also see 1269 Rollandia and 1902 Shaposhnikov, discovered in 1930 and 1972, respectively).
The dark and reddish asteroid is classified as a rare P-type asteroid in the Tholen taxonomic scheme, of which only a few dozens bodies are currently known.[9] It orbits the Sun at a distance of 3.3–3.6 AU once every 6 years and 4 months (2,326 days). Its orbit shows an eccentricity of 0.03 and an inclination of 20 degrees from the plane of the ecliptic.[1] In 2002, a photometric light-curve observation at the U.S. Sonoran Skies Observatory (G94) in Benson, Arizona, gave it a rotation period of 17.100±0.005 hours and an amplitude in brightness of 0.15 magnitude.[6]
According to the surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid has a very low albedo in the range between 0.026 and 0.033, and correspondingly, a diameter between 98.3 and 107.8 kilometers.[3][4][5]
The minor planet is named after the spa town of Abastumani located in the Caucasus Mountains of Georgia. It is more recently the site of a new astronomical observatory.[2]
