No life — too cold for liquid waterMagnetic FieldLow Activity
Why is this a Ice World?Your planet orbits at 0.17 AU from its star, resulting in frigid temperatures of 226K.
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: 0.17 AU (>3 AU) or Temperature <200K✓ Temperature: 226K✓ Water content: 30.4% for ice formation

Contributing Factors
water55
Good water content - mostly frozen
geology60
Some geological activity provides slow nutrient cycling
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry100
All CHNOPS elements present - building blocks of life
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature40
Extreme temperature - very difficult for life
magnetic Field100
Magnetic field provides radiation protection — but the pulsar's beams bathe this orbit in hard X-rays
