72 Pegasi

72 Pegasi is a binary star system in the northern constellation of Pegasus. It is visible to the naked eye as a faint, orange-hued point of light with a combined apparent visual magnitude of 4.97. The system is located approximately 550 light years away from the Sun, based on parallax, but is drifting closer with a radial velocity of −25 km/s.
This is a visual binary with an orbital period of roughly 492 years and an eccentricity of 0.32. The two stars are relatively similar and are about twice the mass of the Sun each. The primary star, 72 Pegasi A, is an evolved K-type giant with a visual magnitude of 5.67. The companion, 72 Pegasi B, is another K-type giant with an apparent magnitude of 6.11, and a separation of about from the primary. 72 Pegasi B is thought to be a binary itself, with a brown dwarf companion in a 4.2-year period.
