Water World

Life DetectedMagnetic FieldModerate Activity

Why is this a Water World?Your planet has abundant oxygen (26.3%) and hydrogen (26.3%), 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: 26.3% + Hydrogen: 26.3% (water-forming elements)✓ Temperature: 257K (habitable range)✓ Distance: 0.74 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
