It can faintly be seen with the naked eye on a dark night, having an apparent visual magnitude of 4.12. Based upon an annual parallax shift of 7.81 mas, it is located around 418 light years from the Sun.
This is an evolved K-type giant star with a stellar classification of K5 III. The measured angular diameter, after correction for limb darkening, is. At the estimated distance of the star, this yields a physical size of about 67 times the radius of the Sun. It is a suspected variable star, with an amplitude of 0.01 magnitude. The star radiates 864 times the solar luminosity from its outer atmosphere with an effective temperature of 4,053 K.
In the next 7500 years, the south Celestial pole will pass close to this stars.
