Why is this a Ice World?Your planet orbits at 1.30 AU from its star, resulting in frigid temperatures of 221K.
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: 1.30 AU (>3 AU) or Temperature <200K✓ Temperature: 221K✓ Water content: 44.1% for ice formation

Contributing Factors
water60
Water present but mostly frozen — shielded under ice and rock, a subsurface refuge could outlast the blast
geology60
Some geological activity provides slow nutrient cycling
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature40
Extreme temperature - very difficult for life
magnetic Field100
Magnetic field provides radiation protection — but the remnant's shock fronts flood this orbit with cosmic rays
