Cygnus system
From Halopedia, the Halo wiki
Template:Ratings The Cygnus System is a Human-controlled system in the Outer Colonies that has not been affected by the Insurrection. [1]
Within its system are two Human colonized worlds. One of which is New Jerusalem, the possible birthplace of Jilan al-Cygni. [2]
Cygnus may be part of the Cygnus constellation.
In real astronomy there is only one nearby star with 'Cygni' in its common name: 61 Cygni, located approximately 14 lightyears from Earth
