Phi1 Pavonis, latinized from φ1 Pavonis, is a single[10] star in the southern constellation of Pavo. It has a yellow-white hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.75.[2] The star is located at a distance of approximately 92 light years away based on parallax. It is drifting closer to the Sun with a radial velocity of −20 km/s.[5]

This is an ordinary F-type main-sequence star with a stellar classification of F0V.[3] It has 1.5[6] times the mass of the Sun and 1.8[1] times the Sun's radius. This is a young star, perhaps 30[8] million years old, and has a high rate of spin with a projected rotational velocity of 150 km/s.[7] It is radiating 8.2[1] times the luminosity of the Sun from its photosphere at an effective temperature of 7,209 K.[1]

Phi1 Pavonis is a candidate debris disk star, although Gray et al. (2006) reported a non-detection of an infrared excess.[3] Nilsson et al. (2010) report a marginal detection, orbiting 74 AU from the host star with a temperature of 57 K and an estimated 3.1±1.7 times the mass of the Moon.[8]
