It is visible to the naked eye as a faint point of light with a combined apparent visual magnitude of 4.35. Based on the system's parallax, it is located 178 light-years (54.7 parsecs) away. The pair are moving away from the Earth with a heliocentric radial velocity of +2 km/s. A telescope reveals it is formed by two yellowish stars of magnitudes 4.7 and 5.8 that are 0.9 arcseconds apart.Monks, Neale Go-To Telescopes Under Suburban Skies https://books.google.com/books?id=waO6tUtfblsC&pg=PA58 58 9781441968517 2010 Springer Science & Business Media New York, New York The two stars orbit each other every 262 years and the orbital eccentricity is 0.74. The components are a magnitude 4.7 evolved giant star of spectral type G8III, and a magnitude 5.8 F-type main-sequence star of spectral type F8V. The former has exhausted the hydrogen at its core, causing it to expand to 8 times the Sun's radius. It is radiating 40 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 5,164 K.
