Why is this a Rocky Terrestrial?Your planet is dominated by silicate (57.1%) and iron (28.6%) content, forming a rocky terrestrial body.
Rocky terrestrial planets are primarily composed of silicate rocks and metals. They're the most common type of small planet in the universe.
Classification Criteria:
✓ Silicon: 57.1% + Iron: 28.6% + Magnesium: 0.0%✓ Mass: 0.3x Earth (terrestrial range)
Habitability ScoreUninhabitable
Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology30
Geologically dead - no nutrient recycling
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry20
Limited organic chemistry potential
atmosphere4
No atmosphere - exposed to radiation and temperature extremes (partially stripped by slow rotation)
temperature5
Scorching temperatures - surface likely molten, no chance for life
magnetic Field30
No magnetic field - vulnerable to solar radiation
