Lava World

Extreme 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: 0.72 AU, 328K equilibrium

Habitability ScoreUninhabitable

Contributing Factors

water0

No water - the recipe has no hydrogen and oxygen to form it

geology50

Extreme volcanic activity may be hazardous (impact-resurfaced crust)

rotation10

Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only

Organic Chemistry50

Carbon and hydrogen present - organic chemistry possible

atmosphere26

Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation) (atmosphere partially stripped by the moon impact)

temperature0

Challenging but potentially habitable temperature (surface remelted by the moon impact - molten regardless of orbit)

magnetic Field30

No magnetic field - vulnerable to solar radiation
