Your guess is almost as good as anyone's Using a ruler or equivalent on the (highly speculative) maps that are available on Wikipedia probably would be as accurate as any other method.1. How many light-years (or parsecs) are we to where the Orion spur connects to the Persius arm?
2. How many light-years (or parsecs) are we to where the Orion spur connects to the Sagittarius arm?
I found three very different answers.3. How many light-years (or parsecs) are we to "Turner 5"
Of course there are appropriate stars on the other side of the cluster, regardless of where it's located (or if it exists). Whether any of their distances have been measured accurately is another matter entirely. To put it another way, any G2V stars in that area of the sky were too dim for Hipparcos to measure.and are there GVs there just beyond "Turner 5" at the end of what seems to be a sort of mini-spiral arm's terminating end?
I'm sure there are some. Further research would be required.4. What major unique sights are to be found 4,000-6,000 light-years along the Orion spur? I mean, what exists only once (in either direction up or down the Orion spur or toward the direction of "Turner 5") in 4,000-6,000 light-years (which is 1,227-1,840.5 parsecs)?

And we figured the G-type stars were roughly 10-15 light years (a.k.a. 3.26-4.6 parsecs) apart. Strictly G2s or even G2Vs though... I'd have to go through the catalogue. Doing the permutation calculation: G-type (yellow) stars could be one of ten classes (ours being 2, meaning a 'yellow' two tenths towards 'orange'), multiplied by 5 luminosity classes (ours being Roman #5 = a dwarf, or more properly, a main sequence star), and you get fifty variations of G-type stars. Ergo, 10-15 light years becomes looking more like 500-750 light years (163-230 parsecs) for distances between just two earth-bearing solar systems of strictly G2V type.
