Den har en kombinerad skenbar magnitud av ca 5,90 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 24,1 mas, beräknas den befinna sig på ett avstånd på ca 135 ljusår (ca 41,5 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 4,6 km/s.iocentrisk radialhastighet på ca 4,6 km/s.

It has a yellow hue and is visible to the naked eye as a dim point of light with a combined apparent visual magnitude of 5.904. The distance to this system is 135 light years as determined using parallax measurements, and is drifting further away with a radial velocity of +4.6 km/s. The binary nature of this star system was first noted by O. C. Wilson and in 1964. It is a double-lined spectroscopic binary with an orbital period of 26.2 days and an eccentricity of 0.22. Both components are similar, G-type main-sequence stars; the primary has a stellar classification of G0V while the secondary has a class of G1V. The masses are similar to each other, and are 28–31% greater than the mass of the Sun. They have low rotation rates which may be quasi-synchronized with their orbital period.si-synchronized with their orbital period.
