Rocky Terrestrial
Magnetic FieldHigh Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (25.6%) and iron (20.9%) 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: 25.6% + Iron: 20.9% + Magnesium: 14.0%✓ Mass: 4.6x Earth (terrestrial range)
Habitability ScoreUninhabitable
Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
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)
temperature0
Near absolute zero - all molecular activity ceases, impossible for life
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1receding0.19% - 15.8 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
Moon 2rings0.10% - 2.8 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
