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:
Composition doesn't match standard planet typesMass: 9534.0x EarthTemperature: 2200K

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
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry50
Carbon and hydrogen present - organic chemistry possible
atmosphere12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature0
Inferno world - temperatures exceed all possibility of life
magnetic Field20
A strong field, but no surface beneath it — there is nothing here for it to shelter

Surface Characteristics
No surface: a deuterium-burning sphere the size of Jupiter and dozens of times its mass, glowing dull red from its own heat
Matched on physical properties only — but pulsar planets are real: the first exoplanets ever confirmed (PSR B1257+12, 1992) orbit a neutron star.Discovered 2020 via imaging · 309 light-years awaySource: NASA Exoplanet Archive
