With an apparent visual magnitude of 4.47,[2] it is visible to the naked eye as a faint point of light.

The distance to this star, as determined using an annual parallax shift of 13.47 mas as seen from the Earth,[1] is around 242 light years.

It is drifting further away with a radial velocity of +39 km/s,[4] having come to within 183 light-years some 805,000 years ago.

[5] This is an evolved K-type giant star with a stellar classification of K3 III,[3] having exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence.

The star is radiating 155 times the Sun's luminosity from its photosphere at an effective temperature of 4,269 K.[6]
