That's really a fantastic way to set up a system map! Very classy and somehow art deco. At some point I may have to shamelessly copy you!

If you're open to suggestions, I do have a couple:
- The first letter of each planet's name being yellow looks odd to my eye; maybe just having the whole thing black would look better?
- What about leaving a bit more space between the info box and the outermost orbit? And keeping the planet images of those outer two inside the overall image instead of overlapping it.

Please take those with a grain of salt; they're only my opinion. Great work, and have some rep!
