Английская Википедия:1554 Yugoslavia
1554 Yugoslavia, provisional designation Шаблон:Mp, is a stony Eunomian asteroid from the middle region of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered by Serbian astronomer Milorad Protić at Belgrade Astronomical Observatory, Serbia, on 6 September 1940.[1] It was named for the former country of Yugoslavia.[2]
Orbit and classification
The asteroid is a member of the Eunomia family, a large group of mostly stony S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun in the central main-belt at a distance of 2.1–3.1 AU once every 4 years and 3 months (1,548 days). Its orbit has an eccentricity of 0.20 and an inclination of 12° with respect to the ecliptic.[3] Yugoslavia was first identified as Шаблон:Mp at Uccle Observatory in 1932. Its observation arc begins 4 year prior to its official discovery observation, with a precovery taken at Nice Observatory in 1936.[1]
Physical characteristics
From 2007 to 2012, several photometric lightcurve observations of Yugoslavia established a well-defined rotation period of 3.89 hours with a brightness variation between 0.64 and 0.74 magnitude (Шаблон:Small).[4][5][6]
According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Yugoslavia measures between 14.73 and 21.39 kilometers in diameter, and its surface has an albedo between 0.070 and 0.269.[7][8][9][10] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 15.94 kilometers with an absolute magnitude of 11.3.[11]
Naming
This minor planet was named after the former country of Yugoslavia.[2] The official Шаблон:MoMP was published by the Minor Planet Center on 30 January 1964 (Шаблон:Small).[12]
