Each star class is divided into 10 subclasses, ranging from 0 (hottest) to 9 (coolest). Stars are also divided into six categories according to luminosity:
Example: Earth's star, Sol would be rated as a G2V, which means that it is a relatively hot (2) G-Class (G) main sequence star (V). So when naming the sub-class of a star they should be named in the following format:
[Letter of class][Temperature number 0 to 9][Luminosity category]
Classes R, N, S, T, Q, and W are not in the main sequence above. They are used for rare star types. More information on these classes will be listed if/when it becomes available in later Paramount-approved products or episodes
