8187 Akiramisawa, provisional designation 1992 XL, is a carbonaceous asteroid from the outer region of the asteroid belt, about 12 kilometers in diameter. It was discovered by Japanese astronomer Satoru Otomo at Kiyosato Observatory on 15 December 1992.[5]
The C-type asteroid orbits the Sun at a distance of 2.6–3.4 AU once every 5 years and 2 months (1,885 days). Its orbit is tilted by 12 degrees to the plane of the ecliptic and shows an eccentricity of 0.12. Photometric light-curve observations at the Palomar Transient Factory in 2013 rendered a rotation period of 5.8 hours[4] and the Collaborative Asteroid Lightcurve Link (CALL) assumes a albedo of 0-06, which is a typical value for carbonaceous asteroids.[1]
The minor planet was named in honour of Japanese botanist Akira Misawa (1942–1994), a professor at Chiba University and a researcher on light pollution on plants.[2]
