Delta Pavonis is a single star in the southern constellation of Pavo. Its name is a Bayer designation that is Latinized from δ Pavonis, and abbreviated Delta Pav or δ Pav. It has an apparent visual magnitude of 3.56, making it a fourth-magnitude star that is visible to the naked eye from the southern hemisphere. Parallax measurements yield an estimated distance of 19.89 light-years (6.10 parsecs) from Earth. This makes it one of the nearest bright stars to the Solar System. It is approaching the Sun with a radial velocity of −23.5 km/s, and is predicted to come as close as 17.8 light-years in around 49,200 years.
