Earth )After chicxulub impact)
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
Habitability ScoreExtremely Harsh
Contributing Factors
water20
Very dry - minimal water
geology50
Extreme volcanic activity may be hazardous (impact-resurfaced crust)
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry20
Limited organic chemistry potential
atmosphere68
Nitrogen atmosphere provides protection but not breathable (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

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 2crashed0.10% - 3.6 radii
Inside the synchronous orbit: tidal decay dragged it down - it struck the planet ages ago.
