(4035) 1986 WD is a carbonaceous leading 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.[10] Currently, it is the second-lowest numbered unnamed minor planet, the lowest being a trailing Jupiter trojan, (3708) 1974 FV1.

Classification and orbit[edit]

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.[1] The first identification was made at Crimea-Nauchnij in 1973, extending the asteroid's observation arc by 13 years prior to its discovery.[10]

Physical characteristics[edit]

In October 2009, a rotational lightcurve was obtained by astronomer Stefano Mottola at the Calar Alto Observatory in Spain. It gave a well-defined rotation period of 13.467±0.08 hours with a brightness variation of 0.21 in magnitude (U=3), superseding a previous result obtained from La Silla's ESO 1-metre telescope in May 1991, that gave a period of 13.52±0.08 hours with an amplitude of 0.20 in magnitude (U=2).[8]

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures between 67 and 69 kilometers in diameter and its surface has an albedo between 0.054 and 0.076.[5][4][6][7] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.060 and a diameter of 68.3 kilometers.[2]

Naming[edit]

As of 2017, (4035) 1986 WD is second lowest numbered minor planet after (3708) 1974 FV1 which has not been named (also see (4035) and (3708)).
