The galaxy has up to 100 stars Each star has from 0 to 10 planets Each planet has from 0 to 2 moons (optional) �Stars have up to 10 planets Each star will have a color (relative temperature). This is expressed as a color (such as Blue-white, white, yellow, orange, red, brown, and black) Each star has an x-y position in the galaxy (up to 100 ly from the center of the galaxy) �Planets can be of three types Ã?¢ââ??‰â?¬Å? Nasty: Rocky or frozen (like Mercury or the planet formerly known as Pluto). Nice: Like Earth or Mars. Gas ball: Like Saturn or Jupiter. Planets have a habitability rating based on their type. Nasty 0-65%, Nice up to 100%, or Gas: only up to 30% (percentages in your galaxy may vary) Planets have a mineral content rated the same way. Nasty 0-100%, Nice: 0-75%, Gas: 0-25% Planets may have up to 2 moons (for xtra credit� Moons are the same as planets Ã?¢ââ??‰â?¬Å? buy only Nasty And moons donÃ?¢ââ??‰â??¢t have moons. Moons are optional for extra credit� S0001 = X:-24 ly, y:89 ly, z:38 ly | Type: Yellow S0001-01 = Distance=0.2 AU | Type: Nasty Habit: 45% | Minerals: 78% S0001-02 = Distance=2.0 AU | Type: Nasty Habit: 52% | Minerals: 11% S0001-02a = Distance=376,420 im | Habit: 47% | Minerals: 19% S0001-02b = Distance=404,266 im | Habit: 5% | Minerals: 40% S0001-03 = Distance=3.0 AU | Type: Nasty Habit: 23% | Minerals: 33% S0001-03a = Distance=534,582 im | Habit: 46% | Minerals: 26% S0001-03b = Distance=370,240 im | Habit: 24% | Minerals: 85% S0001-04 = Distance=4.2 AU | Type: Nasty Habit: 7% | Minerals: 16% S0001-04a = Distance=555,381 im | Habit: 41% | Minerals: 87% S0001-05 = Distance=5.4 AU | Type: Nasty Habit: 68% | Minerals: 10% S0001-05a = Distance=279,099 im | Habit: 7% | Minerals: 19% S0001-06 = Distance=5.9 AU | Type: Nasty Habit: 20% | Minerals: 4% S0001-07 = Distance=6.0 AU | Type: Nice Habit: 57% | Minerals: 47% S0001-08 = Distance=7.0 AU | Type: Nasty Habit: 41% | Minerals: 90% S0001-08a = Distance=510,656 im | Habit: 47% | Minerals: 91% S0001-09 = Distance=8.3 AU | Type: Gaseous Habit: 17% | Minerals: 1% �
