Why is this a Ice World?Your planet orbits at 1.57 AU from its star, resulting in frigid temperatures of 202K.
Ice worlds form beyond the frost line where temperatures are low enough for water and other volatiles to freeze solid. They may have subsurface oceans beneath thick ice shells.
Classification Criteria:
✓ Distance: 1.57 AU (>3 AU) or Temperature <200K✓ Temperature: 202K✓ Water content: 45.8% for ice formation

Contributing Factors
water50
Limited water content — shielded under ice and rock, a subsurface refuge could outlast the blast
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere28
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)
temperature45
Extreme temperature - very difficult for life (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection (a large close moon may help stir the core dynamo (speculative)) — but the remnant's shock fronts flood this orbit with cosmic rays
