Class F geocrystalline planet

Class F silicate, in planetary classification, is a type of planet. These rocky, metallic worlds have also been classified as class G geocrystalline planets on other scales, and are possessed of an oxidizing atmosphere. Lifeforms have a difficult time taking hold on these dry worlds. 


 * The source reference only called this a "class F planet", but another source calls planets of a different type by the same name, leading to the term "silicate" to be used as a descriptor to disambiguate the two terms. In the conflicted source,, planets similar to these worlds are called "class G geocrystalline planets".
