1365 Henyey, provisional designation 1928 RK, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 11 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg Observatory in southern Germany on 9 September 1928, and named for American astronomer Louis Henyey.
Henyey is a member of the Flora family, a large population of stony 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 has an eccentricity of 0.12 and an inclination of 5° with respect to the ecliptic. It was first Identified as A907 GK at Heidelberg in 1907. The body's observation arc, however, begins with its official discovery observation in 1928.
In August 2012, a first rotational light-curve of Henyey was obtained from photometric observations by Daniel Klinglesmith at Etscorn Campus Observatory in New Mexico. It gave a rotation period of 18.986 hours with a brightness variation of 0.23 magnitude (U=2). In November 2016, a divergent period solution of 32.2 hours with a change in brightness of 0.32 magnitude was found by French amateur astronomer René Roy (U=2).
