I'm a sucker for stories set in universes like Niven's Known Space or Cherryh's Alliance/Union, where a lot of the action takes place around stars within around 20 light years of Sol.  So for anyone who might want to use that kind of backdrop, here's a chart showing the distances between some of the more sunlike stars within that distance.

Here are the stars:
  • Alpha and Proxima Centauri/Gliese 559: 4.4 light-years, class G2V
  • Epsilon Eridani/Gliese 144: 10.5 light-years, class K2V
  • Epsilon Indi/Gliese 845: 11.8 light-years, class K5V
  • Tau Ceti/Gliese 71: 11.9 light-years, class G8V
  • 40 Eridani/Gliese 166: 16.5 light-years, class K1V
  • Sigma Draconis/Gliese 764: 18.8 light-years, class K0V
  • Eta Cassiopeiae/Gliese 34: 19.4 light-years, class G3V
  • 82 Eridani/Gliese 139: 19.8 light-years, class G5V
  • Delta Pavonis/Gliese 780: 19.9 light-years, class G8V

And here's the chart:

As I have a couple of offline commitments that will be taking up most of my time for a few weeks, there will be a hiatus in posting... but I'll be back before long!
