Gamma Pavonis, Latinized from γ Pavonis, is a star in the southern circumpolar constellation of Pavo. With an apparent visual magnitude of 4.22,[2] it is a fourth-magnitude star and thereby visible to the naked eye. From parallax observations with the Gaia satellite, the distance to this star has been measured at Script error: No such module "convert".. It is drifting closer to the Sun with a radial velocity of −30 km/s.[1]
The stellar classification of F9 V[3] puts it in the class of F-type main sequence stars that generate energy through the nuclear fusion of hydrogen at the core. It is a metal-poor star, which means it has a low abundance of elements heavier than helium. This star has about 93% of the Sun's mass, and about 106% its radius. It is a brighter star with 146% of the Sun's luminosity, which is it radiating from the outer envelope at an effective temperature of 6,168 K. Its age is estimated at 5.9 billion years.[6]
This star had rank 14 on TPF-C's top 100 target stars to search for a rocky planet in the Habitable Zone, approximately 1.2 AU, or a little beyond an Earth-like orbit.[8]
