Rocky Terrestrial
Magnetic FieldModerate Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (29.4%) and iron (14.7%) 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: 29.4% + Iron: 14.7% + Magnesium: 11.8%✓ Mass: 0.9x Earth (terrestrial range)
Habitability ScoreHighly Habitable
Contributing Factors
water20
Very dry - minimal water
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry84
Core organic elements (CHNO) present (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
magnetic Field100
Magnetic field provides radiation protection
