ι Reticuli, Latinized as Iota Reticuli, is a solitary,[1] orange-hued star in the southern constellation of Reticulum. It is faintly visible to the naked eye, having a combined apparent visual magnitude of +4.97.[2] Based upon an annual parallax shift of 10.22 mas as seen from Earth,[3] it is located around 319 light years from the Sun. At present it is receding from the Sun with a radial velocity of +61 km/s,[4] having come closest to the Sun 883,000 years ago at a distance of 212 light years.[5] Iota Reticuli is moving through the Galaxy at a speed of 80.9 km/s relative to the Sun. Its projected Galactic orbit carries it between 12,300 and 25,100 light years from the center of the Galaxy.[5]

This is an evolved K-type giant star with a stellar classification of K4 III.[6] Having exhausted the supply of hydrogen at its core, the star cooled and expanded off the main sequence; at present it has 24[7] times the girth of the Sun. It is radiating 180[7] times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,290 K.[7]
