Gas Giant
Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 86.0% hydrogen and helium, combined with a mass of 10.1x Earth, which exceeds the gas giant threshold.
Gas giants form when massive cores capture enormous atmospheres of light gases. They typically form beyond the 'frost line' where volatiles can condense.
Classification Criteria:
✓ Hydrogen + Helium: 86.0% (>60% required)✓ Mass: 10.1x Earth (>10x required)
Habitability ScoreExtremely Harsh
Contributing Factors
water60
Water present but mostly frozen
geology40
Extreme volcanic activity may be hazardous
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection
