1365 Henyey, provisional designation 1928 RK, is a stony asteroid from the inner regions of the asteroid belt, about 11 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg Observatory, southern Germany, on 9 September 1928.[6]
The asteroid is a member of the Flora family, a large group of S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,232 days). Its orbit shows an eccentricity of 0.12 and is tilted by 5 degrees to the plane of the ecliptic. It has a rotation period of 18.99 hours[5] and an albedo of 0.28 and 0.24, based on data of the WISE/NEOWISE mission and on assumptions made by the Collaborative Asteroid Lightcurve Link, respectively.[3][4]
It was named after American astronomer Louis Henyey (1910–1970), known for his contributions in the field of stellar structure and stellar evolution. The lunar crater Henyey is also named in his honour.[2]
