The Spiral Arm

It doesn't look that far from here.....

Granted, this is as the crow flies and the distances are different when using the roads.  Some stars are closer by road than shown.  Other stars close together on the Newtonian flats are unreachable by the road network.

Where the words "Orion Spur" appear is the Rift.  The CCW occupies the space between "Sun" and "Orion Spur" while the ULP occupies the region of the Perseus Arm just under the word "Orion."  The La Frontera region is the other side of the Perseus Arm, facing the Outer Arm, shading off into the Wild just above the word "Arm".  The Outer Arm of course constitutes the Rim.

    Yeah but watch out, I hear they have a speed trap around the Orion spur.

    Actually Mike, I'm now paranoid you're listening in on me as I was just needing a map of the galaxy like that. Where did you get it?

    Oh, and where is the "you are here" mark? Is that the "sun" that's labeled on there? (meaning our sun and not one of the others)

      Yes "Sun" is our sun.

      There is an older picture here:
      http://www.atlasoftheuniverse.com/milkyway.jpg
      that shows the Orion Spur as its own arm.

      And a close-up looking rimward here:
