(7641) 1986 TT6 is a carbonaceous Jupiter trojan asteroid in the Greek camp (L4 Lagrangian Point), approximately 69 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]
Physical Characteristics
(7641) 1986 TT6 is a medium-sized asteroid. It has an unusually slow rotation of 22.77 hours.[6] Its low albedo suggests that it is a carbonaceous asteroid.[8] It is classified as a D-type asteroid by Pan-STARRS' large-scale survey.[7]
