Gamma Reticuli (Gamma Ret, γ Reticuli, γ Ret) is a solitaryinterstellar dust.[5]
This is an evolved red giant star, currently on the asymptotic giant branch,[3] with a stellar classification of M4 III.[4] It is a semiregular variable with a period of 25 days.[5] Gamma Reticuli has 1.5−2 times the mass of the Sun, 115 times the Sun's radius,[5] and radiates 1,846 times the solar luminosity from its outer atmosphere at an effective temperature of 3,450 K.[8]
Gamma Reticuli is moving through the Galaxy at a speed of 24.8 km/s relative to the Sun. Its projected Galactic orbit carries it between 24,100 and 39,200 light years from the center of the Galaxy.[12]
