Gamma Pavonis


Gamma Pavonis, Latinized from γ Pavonis, is a star in the southern circumpolar constellation of Pavo. With an apparent visual magnitude of 4.22, 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. It is drifting closer to the Sun with a radial velocity of −30 km/s.
The stellar classification of F9 V 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.
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.
