Proxima C (Osiris)
Ice Giant
Magnetic FieldModerate Activity
Why is this a Ice Giant?Your planet has moderate mass (7.0x Earth) with significant water, carbon, and nitrogen content, characteristic of ice giants.
Ice giants like Uranus and Neptune have icy interiors with thick atmospheres of hydrogen and helium, but not enough to be classified as gas giants.
Classification Criteria:
✓ Mass: 7.0x Earth (5-20x range)✓ Water/Carbon/Nitrogen rich composition
Habitability ScoreExtremely Harsh
Contributing Factors
water60
Water present but mostly frozen
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection
