Rocky Terrestrial
No life — too cold for liquid waterMagnetic FieldHigh Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (12.5%) and iron (7.3%) 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: 12.5% + Iron: 7.3% + Magnesium: 10.4%✓ Mass: 0.7x Earth (terrestrial range)
