    (5025) 1986 TS6, is a carbonaceous Jupiter trojan from the Greek camp and potentially slow rotating asteroid, approximately 58 kilometers in diameter. It was discovered on 5 October 1986, by Slovak astronomer Milan Antal at the Toruń Centre for Astronomy in Piwnice, Poland.[2]

    The dark Jovian asteroid is orbiting in the leading Greek camp at Jupiter's L4 Lagrangian point, 60° ahead of its orbit (see Trojans in astronomy). It orbits the Sun at a distance of 4.8–5.6 AU once every 11 years and 10 months (4,332 days). Its orbit has an eccentricity of 0.07 and an inclination of 11° with respect to the ecliptic.[1]

    Based on a large-scale survey performed by Pan-STARRS, the C-type asteroid has also been rated as a transitional CX-type, an intermediate between the carbonaceous C-type and X-type asteroids.[7] In November 2009, the body was observed in a photometric light-curve survey of 80 Jupiter trojans, which rendered a very long rotation period of 250±25 hours with a brightness variation of 0.2 in magnitude (U=1).[6] However, the Collaborative Asteroid Lightcurve Link (CALL) considers the result as incorrect.[3]

    According to the surveys carried out by the Infrared Astronomical Satellite (IRAS), and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 57.8 and 39.8 kilometers in diameter with an albedo of 0.064 and 0.084, respectively.[1][5] CALL agrees with the results obtained by IRAS, assumes an even lower albedo of 0.04, and calculates a similar diameter of 57.6 kilometers.[3]
