Planetary classification

The standard Federation system of planetary classification categorizes planets based on various factors such as atmospheric composition, surface temperature, vegetation and size. Each class is designated with a letter, for example, Class M (name based on the Vulcan terminology ""Minshara Class") is the most suitable for humanoid long-term habitation.
