I hadn't noticed that the m00n is orbiting Earth at the beginning... then I saw Mercury, Mars, Jupiter and Saturn. There's even some Asteroids between Mars and Jupiter but I can't see Venus, Uranus or Neptune.
Since this is the home system for humans it should be accurate but maybe this is because of the planet settings. More planets in settings will show these missing ones?
Is Earth the only planet with a m00n? There should be many moons around the gas giants, statistically they are the ones with the highest number of moons when compared to solid planets. A m00n may be planet-sized and work exactly as a planet, you should be able to have colonies on some moons.
Also... if the m00n rotates around the Earth I think all planets should orbit around their star. I don't like the idea of a fixed view. The background of the map (the image of the galaxy) should move very slowly, while the star remains fixed. This will give the impression (correctly) that the star is moving in the galaxy but the planets should orbit around their star.
I believe this may lead to interesting tactical consequences should magnetic fields be developed (ship masking), disturbance in traveling and, obviously, death from radiation poisoning in absence of specific shielding technologies.
