Rocky Terrestrial
Magnetic FieldModerate Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (7.5%) 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: 7.5% + Iron: 20.9% + Magnesium: 4.2%✓ Mass: 1.6x Earth (terrestrial range)
Habitability ScoreHabitable
Contributing Factors
water20
Very dry - minimal water
geology90
Active geology recycles nutrients and drives carbon cycle
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry100
All CHNOPS elements present - building blocks of life (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature100
Optimal temperature range for liquid water and life (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection

Moon 1receding0.68% - 55.5 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 2merged1.3% - 63.0 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 3rings0.10% - 2.8 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
