Star System
The two brightest components of this system, Gl 667 A and Gl 667 B, are orbiting each other at an average angular separation of 1.81 arcseconds with a high eccentricity of 0.58. At the estimated distance of this system, this is equivalent to a physical separation of about 12.6 AU, or nearly 13 times the separation of the Earth from the Sun. Their eccentric orbit brings the pair as close as about 5 AU to each other, or as distant as 20 AU, corresponding to an eccentricity of 0.6. This orbit takes approximately 42.15 years to complete and the orbital plane is inclined at an angle of 128° to the line of sight from the Earth. The third component, Gl 667 C, orbits the Gl 667 AB pair at an angular separation of about 30", which equates to a physical separation of about 56 to 215 AU.

“I put the gold star up in the front window
beside the flag. Alterations is what I know
and what I did: hems, gussets and seams.”
