θ Pavonis, Latinized as Theta Pavonis, is a single [9] star in the southern constellation of Pavo. It is just visible to the naked eye as a dim, white-hued star, having an apparent visual magnitude of 5.71. [2] This star is located 213 light years from the Sun based on parallax. [1]
This object is an A-type main-sequence star with a stellar classification of A8V, [3] which indicates it is generating energy through hydrogen fusion at its core. It displays little to no detectable X-ray emission, suggesting a weak corona [10] and, at best, a shallow convection zone. [11] Theta Pavonis is 425 [5] million years old and is spinning rapidly with a projected rotational velocity of 245 km/s. [7] The star has 1.56 [5] times the mass of the Sun and 2.51 [1] times the Sun's radius. It is radiating 17.4 [1] times the luminosity of the Sun from its photosphere at an effective temperature of 7,453 K. [1]
It lies six arc-minutes north of the barred lenticular galaxy NGC 6684.[ citation needed]
