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: 7.9x EarthTemperature: 681K

Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology60
Some geological activity provides slow nutrient cycling
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry54
Carbon and hydrogen present - organic chemistry possible (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
temperature5
Scorching - hot enough to melt lead, though rock stays solid; no chance for life
magnetic Field100
Magnetic field provides radiation protection
