Rocky Terrestrial

Solar System
None Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (56.6%) and iron (37.7%) 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: 56.6% + Iron: 37.7% + Magnesium: 5.7%✓ Mass: 0.3x Earth (terrestrial range)

Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology30
Geologically dead - no nutrient recycling
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry20
Limited organic chemistry potential
atmosphere10
No atmosphere - exposed to radiation and temperature extremes
temperature15
Extremely hot - hostile to known life forms
magnetic Field30
No magnetic field - vulnerable to solar radiation
