Lava World

Magnetic FieldExtreme Activity
Why is this a Lava World?A moon inside the synchronous orbit spiraled in and struck the planet. The impact remelted the surface into a global magma ocean.
Tidal decay drags close-in moons down over millions of years. A large enough impactor liquefies the crust, strips atmosphere, and resets the surface - whatever the orbit's temperature would otherwise allow.
Classification Criteria:
✓ Moon inside the synchronous orbit (tidal decay)✓ Impactor massive enough to remelt the crust- Orbit itself was fine: 1.00 AU, 278K equilibrium

Contributing Factors
water50
Limited water content
geology50
Extreme volcanic activity may be hazardous (impact-resurfaced crust)
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere89
Nitrogen-oxygen atmosphere - breathable and protective (atmosphere partially stripped by the moon impact)
temperature15
Optimal temperature range for liquid water and life (surface remelted by the moon impact - molten regardless of orbit)
magnetic Field100
Magnetic field provides radiation protection
