8187 Akiramisawa, provisional designation Шаблон:Mp, is an Eos asteroid from the outer region of the asteroid belt. It was discovered by Japanese astronomer Satoru Otomo at Kiyosato Observatory Шаблон:Obscode on 15 December 1992.[1] The assumed C-type asteroid has a rotation period of 5.8 hours and measures approximately Шаблон:Convert in diameter. It was named after Japanese botanist Akira Misawa (1942–1994).[2]
Orbit and classification
Akiramisawa is a member the Eos family (Шаблон:Small),[3] the largest asteroid family of the outer main belt consisting of nearly 10,000 known members.[4]Шаблон:Rp It orbits the Sun in the outer asteroid belt at a distance of 2.6–3.4 AU once every 5 years and 2 months (1,886 days). Its orbit has an eccentricity of 0.12 and an inclination of 12° with respect to the ecliptic.[5] In October 1971, it was first identified as Шаблон:Mp at the Chilean Cerro El Roble Station, extending the body's observation arc by 21 years prior to its official discovery observation at Kiyosato.[1]
Naming
This minor planet was named in honour of Japanese botanist Akira Misawa (1942–1994), a professor at Chiba University , who examined the effects of light pollution on plants.[2] The Шаблон:MoMP was published by the Minor Planet Center on 9 January 2001 (Шаблон:Small).[6]
Physical characteristics
A rotational lightcurve of Akiramisawa was obtained from photometric observations made at the Palomar Transient Factory in June 2010. Lightcurve analysis gave a rotation period of Шаблон:Val hours with a high brightness amplitude of 0.90 magnitude (Шаблон:Small).[7] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057, and calculates a diameter of 11.9 kilometers with an absolute magnitude of 13.36.[5]
