Water World

Life DetectedMagnetic FieldHigh Activity

Why is this a Water World?Your planet has abundant oxygen (29.4%) and hydrogen (11.8%), 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: 29.4% + Hydrogen: 11.8% (water-forming elements)✓ Temperature: 282K (habitable range)✓ Distance: 1.04 AU (habitable zone)

Contributing Factors

water90

Good water content with liquid potential

geology90

Active geology recycles nutrients and drives carbon cycle

rotation30

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

Organic Chemistry100

All CHNOPS elements present - building blocks of life (tidal pools cycle wet and dry - a boost for prebiotic chemistry)

atmosphere60

Nitrogen-oxygen atmosphere - breathable and protective (partially stripped by slow rotation)

temperature100

Optimal temperature range for liquid water and life

magnetic Field100

Magnetic field provides radiation protection
