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
rotation30
Very slow rotation - extreme temperature swings between eternal day and night sides
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
temperature0
Inferno world - temperatures exceed all possibility of life
magnetic Field100
Magnetic field provides radiation protection
