Delta Reticuli (Delta Ret, δ Reticuli, δ Ret) is a
.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]
