[2][9] Henyey is a member of the Flora family, a large population of stony S-type asteroids in the inner main-belt.
[9] In August 2012, a first rotational lightcurve of Henyey was obtained from photometric observations by Daniel Klinglesmith at Etscorn Campus Observatory (719) in New Mexico.
[6] 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).
[4][5] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of the family – and calculates a diameter of 11.31 kilometers with an absolute magnitude of 11.9.
