}}{{Starbox end}}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.[3] The distance to this star, as estimated from its annual parallax shift of 6.20 mas,[ is roughly 530 light years from the Sun.]
This is a evolved red giant star on the asymptotic giant branch,[19] having a stellar classification of M2 III.[4] It has expanded to around 56[13] 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.[14]
Delta Reticuli is moving through the Galaxy 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.[1]
