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.

Famous quotes containing the words star and/or system:
“I have drunk ale from the Country of the Young
And weep because I know all things now:
I have been a hazel-tree, and they hung
The Pilot Star and the Crooked Plough
Among my leaves in times out of mind....”
—William Butler Yeats (1865–1939)
“We recognize caste in dogs because we rank ourselves by the familiar dog system, a ladderlike social arrangement wherein one individual outranks all others, the next outranks all but the first, and so on down the hierarchy. But the cat system is more like a wheel, with a high-ranking cat at the hub and the others arranged around the rim, all reluctantly acknowledging the superiority of the despot but not necessarily measuring themselves against one another.”
—Elizabeth Marshall Thomas. “Strong and Sensitive Cats,” Atlantic Monthly (July 1994)
