Rocky Terrestrial
Magnetic FieldExtreme Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (20.7%) and iron (13.6%) 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: 20.7% + Iron: 13.6% + Magnesium: 1.6%✓ Mass: 10.0x Earth (terrestrial range)
Habitability ScoreMarginal
Contributing Factors
water60
Water present but mostly frozen
geology50
Extreme volcanic activity may be hazardous (tidal flexing sustains geologic activity)
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere28
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)
temperature70
Challenging but potentially habitable temperature
magnetic Field100
Magnetic field provides radiation protection

Surface Characteristics
Rocky surface with impact craters, possible volcanic featuresMoonsLife may exist on a moon
Moon 1stable0.013% - 100.0 radii
Small and distant: a quiet, stable companion.
Tidal braking locked the planet to its moon: one face forever moonward.
Moon 2recedingOcean world - life0.10% - 7.6 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 73/100).
Moon 3merged0.30% - 12.0 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 4recedingOcean world - life0.10% - 11.3 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 77/100).
