Gamma Pavonis (γ Pav, γ Pavonis) is a star in the constellation Pavo. It is considered a metal-poor star, which means it has a low abundance of elements heavier than helium. It is also orbiting through the Milky Way at an unusually high velocity relative to nearby stars. Although it appears to have a lower mass than our Sun, it is slightly larger in diameter and has a higher temperature.
This star has rank 14 on TPC-F'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.

In left column are stellar classes of primary members of star systems. ‡Distance error margin extends out of declared distance interval. Bold are systems containing at least one component with absolute magnitude of +8.5 or brighter. Italic are systems possibly located within declared distance interval, but probably not.
