Ice Giant

Magnetic FieldModerate Activity

Why is this a Ice Giant?Your planet has moderate mass (7.7x 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: 7.7x Earth (5-20x range)✓ Water/Carbon/Nitrogen rich composition

Habitability ScoreUninhabitable

Contributing Factors

water60

Water present but mostly frozen

geology90

Active geology recycles nutrients and drives carbon cycle

rotation10

Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only

Organic Chemistry80

Core organic elements (CHNO) present

atmosphere12

Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)

temperature0

Near absolute zero - all molecular activity ceases, impossible for life

magnetic Field100

Magnetic field provides radiation protection

MoonsLife may exist on a moon

Moon 1rings0.010% - 1.6 radii

Inside the Roche limit (1.92 planet radii): torn apart into a ring system.

Moon 2recedingOcean world - life0.052% - 5.0 radii

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).

Tidal braking locked the planet to its moon: one face forever moonward.

Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 51/100).
