1118 Hanskya, provisional designation 1927 QD, is a dark asteroid from the asteroid belt, about 77 kilometers in diameter. It was discovered by Russian astronomers Sergey Belyavsky and Nikolaj Ivanov at the Crimean Simeiz Observatory on 29 August 1927. The asteroid was independently discovered by two other prolific astronomers in the field, namely Karl Reinmuth at the German Heidelberg Observatory – who observed the body only one day later and announced it first – and by Belgian astronomer Eugène Delporte at the Royal Observatory, Uccle on 17 September.
The main-belt asteroid orbits the Sun at a distance of 3.1–3.4 AU once every 5 years and 9 months. Its rotation period has been measured to take about 15 1⁄2 hours. It has a low geometric albedo of only 0.047, according to numerous observations made by the Infrared Astronomical Satellite (IRAS).
It was named in honor of the 25th anniversary of the death of the first astronomer of the Simeiz Observatory, Aleksey Pavlovitch Hansky.
