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: 8.0x EarthTemperature: 188K
Habitability ScoreUninhabitable

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 Chemistry50
Carbon and hydrogen present - organic chemistry possible
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection — but the pulsar's beams bathe this orbit in hard X-rays

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 radial velocity · 19 light-years awaySource: NASA Exoplanet Archive
