Why is this a Gas Wisp?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: 0.1x EarthTemperature: 278K

Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology30
Geologically dead - no nutrient recycling
rotation60
Fast rotation - strong global wind patterns and weather systems, but manageable
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere10
No atmosphere - exposed to radiation and temperature extremes
temperature100
Optimal temperature range for liquid water and life
magnetic Field30
No magnetic field - vulnerable to solar radiation
