Why is this a Rocky Terrestrial?Your planet is dominated by silicate (21.8%) and iron (17.8%) 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: 21.8% + Iron: 17.8% + Magnesium: 11.9%✓ Mass: 3.5x Earth (terrestrial range)
Habitability ScoreHabitable
Contributing Factors
water60
Water present but mostly frozen
geology100
Active geology recycles nutrients and drives carbon cycle (tidal flexing sustains geologic activity)
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere28
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)
temperature40
Extreme temperature - very difficult for life
magnetic Field100
Magnetic field provides radiation protection

Surface Characteristics
Rocky surface with impact craters, possible volcanic featuresMoons
Moon 1rings0.10% - 2.8 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 2receding0.10% - 7.5 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 3receding0.10% - 19.8 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
