It is visible to the naked eye as a faint, yellow-hued star with an apparent visual magnitude of 4.72. The system is located approximately 177 light years away from the system based on parallax. It is receding from the Earth with a heliocentric radial velocity of +36 km/s, having come to within 9.636 pc ly 0 off out some 1.4 million years ago.Bailer-Jones C. A. L.

It is a red clump giant, which indicates it is on the horizontal branch and is generating energy through helium fusion at its core.Alves David R.

The star is about one billion years old with 1.05 times the mass of the Sun and 8.9 times the Sun's radius. It is radiating 43 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,750 K. The secondary member, component B, is a magnitude 11.2 star at an angular separation of 2.1 arcsecond from the primary. Four visual companions have been reported. These are component C, at magnitude 13.2 and separation 30.7", D, at magnitude 8.9 and separation 57.8", E, at magnitude 9.37 and separation 70.1", and F, at magnitude 10.74 and separation 114.1".2001AJ....122.3466M 10.1086/323920 The 2001 US Naval Observatory Double Star CD-ROM.
