(7641) 1986 TT₆ is a Jupiter Trojan asteroid in the Greek camp (L₄ Lagrangian Point). It was discovered on October 5, 1986, at the Piwince Observatory by Milan Antal.^[2]

Physical Characteristics

(7641) 1986 TT₆ is a medium-sized asteroid. It has an unusually slow rotation of 22.77 hours. Its low albedo suggests that it is a carbonaceous asteroid.^[3]
