Delta Reticuli (Delta Ret, δ Reticuli, δ Ret) is a star in the southern constellation of Reticulum. It is visible to the naked eye, having an apparent visual magnitude of 4.60. [2] The distance to this star, as estimated from its annual parallax shift of 6.20 mas, [1] is roughly 530 light-years from the Sun.
This is an evolved red giant star on the asymptotic giant branch, [3] having a stellar classification of M2 III. [4] It has expanded to around 56 [8] times the radius of the Sun and radiates 1,100 times the solar luminosity from its cool outer atmosphere at an effective temperature of 3,891 K. [9]
Delta Reticuli is moving through the Milky Way at a speed of 13.3 km/s relative to the Sun. Its projected galactic orbit carries it between 22,700 and 30,400 light-years from the center of the galaxy. [11]
