Surface. Rocky surface with impact craters, possible volcanic features
Rocky Terrestrial
✦ solar system times 2
Your planet is dominated by silicate (44.1%) and iron (14.7%) content, forming a rocky terrestrial body.None Activity
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: 44.1% + Iron: 14.7% + Magnesium: 14.7%✓ Mass: 0.1x 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
Minimal or none
No atmosphere - exposed to radiation and temperature extremes (partially stripped by slow rotation)temperature14
Extremely hot - hostile to known life forms
magnetic Field30
No magnetic field - vulnerable to solar radiation
