My second idea for Asgardia's flag. The asgardian emblem in the middle surrounded by our 8 planets. Starting from the 12 o'clock position clock-wise: Green (Earth), Gray (Mercury), Light blue (Uranus), Cream (Saturn), Red (Mars), Warm Gray (Jupiter), Blue (Neptun) and Orange (Venus).
Every planet is (or will be) a part/member of Asgardia and its protection shield.

In addition there are the 172 moons from the big eight (our solar system contains more than 400 satellites!) that also should be members.
