Gas Giant

Magnetic FieldExtreme Activity

Why is this a Gas Giant?Your planet has 85.0% hydrogen and helium, combined with a mass of 95.0x 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: 85.0% (>60% required)✓ Mass: 95.0x Earth (>10x required)

Contributing Factors

water50

Limited water content

geology40

Extreme volcanic activity may be hazardous

rotation30

Very slow rotation - severe temperature swings between eternal day and night sides

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

temperature10

Frozen world - minimal potential for complex life

magnetic Field100

Magnetic field provides radiation protection
