Another big hex

I thought I should try a variation on the big hex style. This time for an important star system in the Spinward Marches.

All planets (except Cipango) was made with GIMP plug-ins. The Cipango ring system was made with the planet rings GIMP plug-in. The planet Cipango was made from an old texture that I have used for other maps of Cipango.


The distances for the planets from their “sun” Cipango-Taiyoo is calculated using a modified Titius-Bode law. Using the formula below for the Cipango system:

a = 0.7 + 0.2 · 2 m

For our solar system the formula is:

a = 0.4 + 0.3 · 2 m

Where a is the distance in AU, and m is the orbit number. (Where m is 1 for Earth.) The modification of the Titius-Bode law was needed to fit two planet orbits into the habitable zone. This gives the Cipango system a total of 3 garden worlds.
