Why is this a Brown 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:

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 Chemistry20
Limited organic chemistry potential
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
temperature40
Extreme temperature - very difficult for life
magnetic Field100
Magnetic field provides radiation protection
