Английская Википедия:1779 Paraná
1779 Paraná, provisional designation Шаблон:Mp, is an asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter.
The asteroid was discovered on 15 June 1950, by Argentine astronomer Miguel Itzigsohn at the La Plata Astronomical Observatory in La Plata, capital of the province of Buenos Aires.[1] It was named for the Paraná River in South America.[2]
Orbit and classification
Paraná orbits the Sun in the inner main-belt at a distance of 1.8–2.5 AU once every 3 years and 3 months (1,172 days). Its orbit has an eccentricity of 0.16 and an inclination of 1° with respect to the ecliptic.[3]
As no precoveries were taken, and no prior identifications were made, ParanáШаблон:'s observation arc begins with its official discovery observation in 1950.[1] Paraná has also been cataloged by the Palomar–Leiden survey and received the survey designation Шаблон:Mp (PLS6116).[3][1]
Physical characteristics
Diameter and albedo
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Paraná measures 4.09 kilometers in diameter and its surface has an albedo of 0.221.[4] Based on a magnitude-to-diameter conversion, using an albedo in the range of 0.05 to 0.25 and a magnitude of 14.1, the asteroid's generic diameter is between 4 and 9 kilometers.[5]
Rotation period
As of 2017, ParanáШаблон:'s spectral type, rotation period and shape remain unknown.[3][6]
Naming
This minor planet was named for a large and 4,880-kilometers long Paraná River that runs through northern Argentina, Brazil and Paraguay. It is a major tributary to the La Plata river, where the city of La Plata and the discovering observatory are located (also see 1029 La Plata).[2] The official naming citation was published by the Minor Planet Center on 8 April 1982 (Шаблон:Small).[7]
