main sequence dwarfstar in theconstellation Hercules. TheFlamsteed designation for this star comes from the publication "Historia Coelestis Britannica" byJohn Flamsteed . It is the 72nd star in Flamsteed list of stars in the constellation Hercules.Based on its
spectral classification of G0 V, it is similar in mass and luminosity to theSun .Parallax measurements show this star to be about 47light year s from thesolar system . Thephotosphere shows an effectivetemperature of 5,625 °Kcite journal | author = G. Israelian, R.J.L. García, R.

The first is a visual magnitude 9.7 star located 289.1
arc second s away. The second is only separated by 8.7 arc seconds, and is magnitude 12.9. [cite journal | author = C.E. Worley, G.G.
