Английская Википедия:1450 Raimonda
1450 Raimonda, provisional designation Шаблон:Mp, is a background asteroid from the central regions of the asteroid belt, approximately 15 kilometers in diameter. It was discovered on 20 February 1938, by astronomer Yrjö Väisälä at the Iso-Heikkilä Observatory in Turku, Finland.[1] The asteroid was named after Dutch astronomer Jean Jacques Raimond, Jr.[2]
Orbit and classification
Raimonda is a non-family asteroid of the main belt's background population.[3] It orbits the Sun in the central asteroid belt at a distance of 2.2–3.1 AU once every 4 years and 3 months (1,542 days). Its orbit has an eccentricity of 0.17 and an inclination of 5° with respect to the ecliptic.[4]
The body's observation arc begins with its first identification as Шаблон:Mp at Heidelberg Observatory in October 1915, more than 22 years prior to its official discovery observation at Turku.[1]
Physical characteristics
Raimonda is an assumed stony S-type asteroid,[5] despite its rather low albedo.
Rotation period and poles
In December 2004, a rotational lightcurve of Raimonda was obtained from photometric observations at the Oakley (Шаблон:Small) and Tenagra Observatory (Шаблон:Small). Lightcurve analysis gave a rotation period of 12.66 hours with a brightness amplitude of 0.64 (or 0.57 at LCDB) magnitude (Шаблон:Small), indicative of an elongated shape.[6]
In 2013, a lightcurve was modeled from photometric data collected by the Uppsala Asteroid Photometric Catalogue, the Palomar Transient Factory survey, and individual observers, as well as sparse-in-time photometry from the United States Naval Observatory Flagstaff Station, the Catalina Sky Survey in Tucson, and the Roque de los Muchachos Observatory at La Palma. Modelling gave a similar period 12.6344 hours. The study also determined two spin axis of (231.0°, −56.0°) and (71.0°, −60.0°) in ecliptic coordinates (λ, β).[7]
Diameter and albedo
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, Raimonda measures between 14.76 and 20.80 kilometers in diameter and its surface has an albedo between 0.074 and 0.1387.[8][9][10][11][12]
The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0976 and a diameter of 14.75 kilometers based on an absolute magnitude of 12.3.[5]
Naming
This minor planet was named after Jean Jacques Raimond, Jr. (1903–1961), a Dutch astronomer who was the president of the Dutch Astronomical Society (Шаблон:Lang-nl; Netherlands Association for Meteorology and Astronomy) and director of the Zeiss planetarium at The Hague.[2]
The naming was suggested by Belgian astronomer Jean Meeus, and the official Шаблон:MoMP was published by the Minor Planet Center on 1 February 1965 (Шаблон:Small).[13] The lunar crater Raimond was also named in his honor.[2]
