26 Draconis
26 Draconis is a triple star system in the constellation Draco, located 46 light years from the Sun. Two of the system components, A and B, form a spectroscopic binary that completes an orbit every 76 years. The composite spectral classification of the AB pair is G0V, which decomposes to individual spectral types F9V and K3V. A 1962 study estimated the masses of these two stars as 1.30 and 0.83 times the mass of the Sun, respectively. The stars are considered moderately metal-poor compared to the Sun, which means they have a lower proportion of elements other than hydrogen or helium. Gliese 685 

The third component, GJ 685, is a red dwarf spectral classification of M0V. As of 1970, this star is separated by 737.9 arc seconds from the AB pair and they share a common proper motion. The Star GJ 685 has one known planet orbit that was detected by radial velocity. The space velocity components of 26 Draconis are U = +36.5, V = −4.3 and W = −21.8 km/s. This system is on an orbit through the Milky Way galaxy that has an eccentricity of 0.14, taking it as close as  and as far as  from the galactic core. The inclination of this orbit carries the star system as much as  above the plane of the galactic disk. This system may be a member of the Ursa Major moving group. References
