Orion Arm

The Orion Arm, also known as the Orion Region, Local Arm, or Orion Spur, is the colloquial title given to the extent of human exploration and settlement across interstellar space. Though its name derives from the Orion-Cygnus Arm of the Milky Way Galaxy, it denotes just a small segment of the spiral arm proper. In a broader context, it serves as a shorthand for referring to the human civilization as a whole.
