Rocky Terrestrial
Low Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (34.2%) and iron (20.5%) content, forming a rocky terrestrial body.
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: 34.2% + Iron: 20.5% + Magnesium: 13.7%✓ Mass: 0.4x Earth (terrestrial range)
Habitability ScoreUninhabitable
Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology60
Some geological activity provides slow nutrient cycling
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)
temperature40
Extreme temperature - very difficult for life
magnetic Field30
No magnetic field - vulnerable to solar radiation
