Barren

Magnetic FieldModerate Activity
Why is this a Barren?Your planet has an unusual composition that doesn't fit standard classifications, or lacks the elements needed for complex geological processes.
Barren worlds can form from uncommon element combinations or may be remnants of larger bodies that lost their atmospheres and volatile materials.
Classification Criteria:
Composition doesn't match standard planet typesMass: 1.0x EarthTemperature: 278K

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 Chemistry100
All CHNOPS elements present - building blocks of life
atmosphere50
CO₂ atmosphere with moderate greenhouse effect
temperature100
Optimal temperature range for liquid water and life
magnetic Field100
Magnetic field provides radiation protection
