Английская Википедия:1827 Atkinson
1827 Atkinson, provisional designation Шаблон:Mp, is a background asteroid from the central regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 7 September 1962, by IU's Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States.[1] The asteroid was named after British astronomer Robert d'Escourt Atkinson.[2]
Orbit and classification
Atkinson is not a member of any known asteroid family.[3] It orbits the Sun in the central main-belt at a distance of 2.2–3.2 AU once every 4 years and 6 months (1,629 days). Its orbit has an eccentricity of 0.18 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 Uccle Observatory in November 1931, almost 31 years prior to its official discovery observation at Goethe Link.[1]
Physical characteristics
In the Tholen classification, Atkinson is similar to a dark D-type asteroid, though with an unusual spectrum (DU).[4] This strongly disagrees with the albedo obtained by the Wide-field Infrared Survey Explorer (WISE), which indicates that is rather a stony S-type asteroid.[5]
Rotation period
As of 2017, no rotational lightcurve of Atkinson has been obtained from photometric observations. The asteroid's rotation period, shape and poles remain unknown.[4][3]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Atkinson measures 8.855 kilometers in diameter and its surface has an albedo of 0.249.[5]
Naming
This minor planet was named after British astronomer, physicist and inventor, Robert d'Escourt Atkinson (1898–1982), noted for his contributions to fundamental astronomy. Atkinson pioneered in studying nuclear energy-generation in the Sun and stars.[2] The official Шаблон:MoMP was published by the Minor Planet Center on 15 October 1977 (Шаблон:Small).[6]
