Lava World

Extreme Activity
Why is this a Lava World?Your planet's proximity to its star (0.10 AU) results in extreme surface temperatures of 15633K.
Lava worlds orbit so close to their stars that rocky surfaces melt into oceans of molten rock. Recent planet formation can also create temporary lava worlds.
Classification Criteria:
✓ Temperature: 15633K (>1000K)
Habitability ScoreUninhabitable

Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it (water stripped by extreme rotation)
geology40
Extreme volcanic activity may be hazardous
rotation0
Catastrophic rotation - centrifugal forces would destroy surface structures and prevent atmosphere retention
Organic Chemistry20
Limited organic chemistry potential
atmosphere1
No atmosphere - exposed to radiation and temperature extremes (severely compromised by extreme rotation)
temperature0
Inferno world - temperatures exceed all possibility of life
magnetic Field30
No magnetic field - vulnerable to solar radiation
