The estimated distance to this star, based upon an annual parallax shift of 3.30±0.35 mas, is roughly 1,000 light years. It is moving further away with a heliocentric radial velocity of +29 km/s. The star made its closest approach to the Sun some 8.7 million years ago at a separation of around 362 ly (111.12 pc).
  
  Roughly 40 million years old, this is an evolved K-type giant star with a stellar classification of K2+ IIIa CN0.5 Ca1. The suffix notation indicates overabundances of calcium and the cyanide molecule have been found in the spectrum of the stellar atmosphere. The star has 7.4 times the mass of the Sun and has expanded to 28 times the Sun's radius. It is radiating 2,317 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,200 K.
