Ferria

==Information==
Ferria (also known as Iron planets) is a type of planet that contains more iron or nickel in its core, it requires above 50% of the planets composition, our Solar System's first planet Mercury is a good example. Most of the Iron planets are barely above the 50% requirement. By mass, iron ranks after hydrogen, helium, oxygen, carbon, and neon as the sixth most prevalent element in the universe as a whole.
==Formation and Life possibility==
A planet with more iron/nickel can make the planet more smaller and denser. They can be found more abundantly in white dwarf systems due to its mantle being stripped away from the powerful supernovae. Ferria planets can form due to another large celestial object stripping away its mantle, another way for Ferria planets to form is in massive stars, presumably the protoplanetary disk is rich in iron or nickel, or either orbits close to its parent star.
It is very unlikely that they will ever form a magnetic field or tectonic plates, making developing life on Ferrias or terraforming Ferrias much more difficult, this is because they cool down quickly subsequent to forming than Terras. Despite this, life on Ferria planets is possible (Ironically, most of the Ferrias are habitable worlds with life complexity equivalent to Earth's, don't ask why). In a geologic time scales, Iron planets with body of liquid water in the surface is thought to be unstable and may be replaced by other exotic volatiles such as iron carbonyl.
