Rocky Terrestrial

High Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (15.9%) and iron (12.2%) content, forming a rocky terrestrial body. Its hydrogen and oxygen stock collects as scattered seas across the rocky crust.
Rocky terrestrial planets are primarily composed of silicate rocks and metals. They're the most common type of small planet in the universe.
Classification Criteria:
✓ Silicon: 15.9% + Iron: 12.2% + Magnesium: 5.3%✓ Mass: 3.8x Earth (terrestrial range)

Contributing Factors
water100
Abundant liquid water at surface temperature
geology90
Active geology recycles nutrients and drives carbon cycle
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry20
Limited organic chemistry potential
atmosphere28
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)
temperature100
Optimal temperature range for liquid water and life
magnetic Field30
No magnetic field - vulnerable to solar radiation
