Water World

Life DetectedMagnetic FieldHigh Activity
Why is this a Water World?Your planet has abundant oxygen (25.2%) and hydrogen (10.8%), creating extensive water coverage while in the habitable temperature zone.
Water worlds have deep global oceans covering most or all of their surface. They form when planets have high water content and orbit in the habitable zone.
Classification Criteria:
✓ Oxygen: 25.2% + Hydrogen: 10.8% (water-forming elements)✓ Temperature: 254K (habitable range)✓ Distance: 0.24 AU (habitable zone)

Contributing Factors
water60
Water present but mostly frozen
geology90
Active geology recycles nutrients and drives carbon cycle
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)
atmosphere100
Nitrogen-oxygen atmosphere - breathable and protective
temperature70
Challenging but potentially habitable temperature
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1rings10% - 2.8 radii

Inside the Roche limit (2.80 planet radii): torn apart into a ring system.

Moon 2merged0.035% - 7.5 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 3merged0.10% - 7.7 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 4merged0.10% - 9.3 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 5merged0.012% - 8.9 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 6merged0.030% - 8.2 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 7receding0.10% - 26.2 radii

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