Английская Википедия:1513 Mátra
1513 Mátra, provisional designation Шаблон:Mp, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 10 March 1940, by Hungarian astronomer György Kulin at Konkoly Observatory in Budapest, Hungary.[1] It was later named after the Mátra mountain range.[2]
Orbit and classification
Mátra is a member of the Flora family, a large group of stony S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 2.0–2.4 AU once every 3 years and 3 months (1,186 days). Its orbit has an eccentricity of 0.10 and an inclination of 4° with respect to the ecliptic.[3]
One day prior to MátraШаблон:'s official discovery observation at Konkoly, a precovery was taken at Nice Observatory. However, the body's observation arc begins 10 years later in 1950, when it was observed at the La Plata Observatory in Argentina.[1]
Physical characteristics
Rotation period
American astronomer Richard P. Binzel obtained a rotational light-curve of Mátra from photometric observation in the 1980s. It gave a tentative rotation period of 24 hours with a brightness variation of 0.1 magnitude (Шаблон:Small).[4] As of 2017, a secure period still has yet to be determined.[5]
Diameter and albedo
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Mátra measures between 4.96 and 6.60 kilometers in diameter and its surface has an albedo between 0.189 and 0.34.[6][7][8]
The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from the family's largest body and namesake, the asteroid 8 Flora – and calculates a diameter of 5.85 kilometers with an absolute magnitude of 13.33.[5]
Naming
This minor planet was named after the Mátra mountain range in northern Hungary, where the outstation of the discovering Konkoly Observatory is located.[2] The official naming citation was published by the Minor Planet Center on 1 February 1980 (Шаблон:Small).[9]
