(4035) 1986 WD is a carbonaceous Jupiter trojan from the Greek camp, approximately 68 kilometers in diameter. It was discovered on 22 November 1986, by Japanese astronomers Kenzo Suzuki and Takeshi Urata at the Toyota Observatory (881) in Japan. The C-type Jovian asteroid orbits the Sun at a distance of 5.0–5.6 AU once every 12 years and 2 months (4,438 days). Its orbit has an eccentricity of 0.06 and an inclination of 12° with respect to the ecliptic. The first identification was made at Crimea-Nauchnij in 1973, extending the asteroid's observation arc by 13 years prior to its discovery.
