Gas Dwarf

Low Activity
Why is this a Gas Dwarf?Your planet has an unusual composition that doesn't fit standard classifications, or lacks the elements needed for complex geological processes.
Barren worlds can form from uncommon element combinations or may be remnants of larger bodies that lost their atmospheres and volatile materials.
Classification Criteria:
Composition doesn't match standard planet typesMass: 10.0x EarthTemperature: 263K
Habitability ScoreExtremely Harsh

Contributing Factors
water60
Water present but mostly frozen
geology60
Some geological activity provides slow nutrient cycling
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry20
Limited organic chemistry potential
atmosphere12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature70
Challenging but potentially habitable temperature
magnetic Field30
No magnetic field - vulnerable to solar radiation
