402 Chloë (prov. designation: A895 FB or 1895 BW) is a large main-belt asteroid. It was discovered by French astronomer Auguste Charlois on 21 March 1895 from Nice.[2] This asteroid is orbiting the Sun at a distance of 2.56 astronomical unit|AU with a period of 4.09 years and an eccentricity of 0.11. The orbital plane is inclined at an angle of 11.8° to the plane of the ecliptic.[2]
This asteroid spans a girth of approximately 54 km.[2] It is classified as a K-type asteroid and is a Barbarian.[3] Analysis of the asteroid light curve, based on photometric data collected during 2009, show a rotation period of 10.664±0.001 h with a brightness variation of 0.30±0.01 in magnitude.[4]
