π Pavonis, Latinized as Pi Pavonis, is a candidate astrometric binary^[11] star system in the constellation Pavo. It is a white-hued star that is visible to the naked eye as a faint point of light with an apparent visual magnitude of 4.33.^[2] The distance to this object is 130 light years based on parallax,^[1] but it is drifting closer to the Sun with a radial velocity of −15.6 km/s.^[5]

The visible component is an chemically peculiar star that displays an abundance anomaly of strontium.^[12]^[13] Grey et al. (1989) classify it as kA4hF0mF2 III,^[3] matching a giant Am star with the calcium K line of an A4 star, the hydrogen lines of a cooler F0 star, and the metal lines of a F2 star. However, Loden and Sundman (1989) don't consider it to be a giant and list it as an Ap star.^[12] It is 630^[6] million years old with 2.15^[6] times the mass of the Sun and 2.8^[7] times the Sun's radius. The star is radiating 24.7^[7] times the Sun's luminosity from its photosphere at an effective temperature of 7,632 K.^[7]
