1827 Atkinson, provisional designation 1962 RK, 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 ProgramatGoethe Link Observatory near Brooklyn, Indiana, United States.[4] The asteroid was named after British astronomer Robert d'Escourt Atkinson.[2]

Orbit and classification

[edit]

Atkinson is not a member of any known asteroid family.[5] 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.[1]

The body's observation arc begins with its first identification as 1931 VCatUccle Observatory in November 1931, almost 31 years prior to its official discovery observation at Goethe Link.[4]

Physical characteristics

[edit]

In the Tholen classification, Atkinson is similar to a dark D-type asteroid, though with an unusual spectrum (DU).[1] 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.[3]

Rotation period

[edit]

As of 2017, no rotational lightcurveofAtkinson has been obtained from photometric observations. The asteroid's rotation period, shape and poles remain unknown.[1][5]

Diameter and albedo

[edit]

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.[3]

Naming

[edit]

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 naming citation was published by the Minor Planet Center on 15 October 1977 (M.P.C. 4236).[6]
