The two brightest stars in this system, GJ 667 A and GJ 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. [note 1] 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 star, GJ 667 C, orbits the GJ 667 AB pair at an angular separation of about 30″, which equates to a minimum separation of 230 AU.
