Rocky Terrestrial

None Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (34.9%) and iron (23.3%) 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: 34.9% + Iron: 23.3% + Magnesium: 14.0%✓ Mass: 0.1x Earth (terrestrial range)

Contributing Factors
water20
Very dry - minimal water
geology30
Geologically dead - no nutrient recycling
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature5
Scorching temperatures - surface likely molten, no chance for life
magnetic Field30
No magnetic field - vulnerable to solar radiation
