Solar System Generator
Detailed descriptions of a star and its orbiting bodies. May or may not generate life-supporting sytems.
For reference, our solar system's star, called "The Sun", is a G-Type Main Sequence Star. AU stands for Astronomical Unit and is a unit of length; approximately the distance between the Earth and the Sun.
The letter refers to how hot the star is, with the letters, in order of hottest to coolest, being O, B, A, F, G, K, M (Don't ask...I didn't make up this classification system!)
The color also relates to the temperature of the star; the hotter, the bluer.
