85 Pegasi is a

apastron. 85 Pegasi B may itself be a binary, with a close, faint red dwarf companion (designated 85 Pegasi Bb) separated by 2 AU from the primary (designated 85 Pegasi Ba). The mass would be 11% solar mass (M☉). All components in the star system including Star A are smaller, cooler and less massive, luminous, and metallic than the Sun and 51 Pegasi
.

An infrared excess has been detected around the primary, most likely indicating the presence of a

AU. The temperature of this dust is below 25 K.[5]
