HD 182681 (186 G. Sagittarii) is a single,

light years from the Sun. It is moving away from the Sun with a radial velocity of 1.40 km/s.[4]

This is a

projected rotational velocity of 277 km/s.[6] It has an infrared excess, which suggests a debris disk is orbiting the star at a radius of 47 AU with a mean temperature of 90 K.[12]
