Why is this a Ice World?Your planet orbits at 0.40 AU from its star, resulting in frigid temperatures of 203K.
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: 0.40 AU (>3 AU) or Temperature <200K✓ Temperature: 203K✓ Water content: 25.2% for ice formation

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
