Eta Circini
Eta Circini is a solitary star located in the southern constellation of Circinus. Its name is a Bayer designation that is Latinized from η Circini, and abbreviated Eta Cir or η Cir. This star is faintly visible to the naked eye with an apparent visual magnitude of 5.17. The distance to this star, as determined from an annual parallax shift of 11.8 mas, is around 277 light years. The star is drifting further away from the Sun with a line of sight velocity component of 45 km/s.
This is an evolved G-type giant star with a stellar classification of G8 III. It is 414 million years old with 2.9 times the mass of the Sun and 10.7 times the Sun's radius. The star is radiating 78 times the solar luminosity from its enlarged photosphere at an effective temperature of 5,250 K.
