Английская Википедия:3771 Alexejtolstoj
3771 Alexejtolstoj (provisional designation Шаблон:Mp) is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 3.7 kilometers in diameter. It was discovered on 20 September 1974, by Russian–Ukrainian astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula.[1] The asteroid was named after writer Aleksey Nikolayevich Tolstoy.[2]
Orbit and classification
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 in the inner main-belt at a distance of 1.8–2.6 AU once every 3 years and 4 months (1,212 days). Its orbit has an eccentricity of 0.17 and an inclination of 5° with respect to the ecliptic.[3] It was first identified as Шаблон:Mp at Heidelberg Observatory in 1954. The body's observation arc begins at Nauchnyj with its official discovery observation made in 1974.[1]
Physical characteristics
A fragmentary rotational lightcurve was obtained from photometric observation made at the Palomar Transient Factory in California in December 2011. The lightcurve gave a provisional rotation period of Шаблон:Val hours with a low brightness amplitude of 0.08 in magnitude (Шаблон:Small).[4] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of its orbital family – and calculates a diameter of 3.7 kilometers.[5]
Naming
This minor planet was named after Soviet writer and public figure, Aleksey Nikolayevich Tolstoy (1883–1945).[2] The official naming citation was published by the Minor Planet Center on 19 October 1994 Шаблон:Small.[6]
