Planet, moons and orbits drawn to one scale; the smallest moons are enlarged so they can be seen.
Surface. No solid surface - a deep volatile envelope over a supercritical water mantle and hot-ice interior
Ice Giant
Magnetic FieldExtreme Activity
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: 12.0x Earth (5-20x range)✓ Water/Carbon/Nitrogen rich composition
Habitability ScoreExtremely Harsh
Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology40
Extreme volcanic activity may be hazardous
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere30
Hydrogen and helium with water, methane, and ammonia ices
Hydrogen-rich atmosphere typical of gas giantstemperature61
Cold - water freezes much of the year; challenging but potentially habitable (extreme seasons: at 56° the poles swing between months-long day and night: −6% habitability)
magnetic Field100
Magnetic field provides radiation protection
