Rocky Terrestrial
Magnetic FieldModerate Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (38.5%) and iron (7.7%) 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.
✓ Silicon: 38.5% + Iron: 7.7% + Magnesium: 7.7%✓ Mass: 1.0x Earth (terrestrial range)

Contributing Factorswater50
Water present but likely as steamgeology90
Active geology recycles nutrients and drives carbon cyclerotation30
Very slow rotation - extreme temperature swings between eternal day and night sidesOrganic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)atmosphere42
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)temperature5
Scorching - hot enough to melt lead, though rock stays solid; no chance for lifemagnetic Field100
