Rocky Terrestrial
Magnetic FieldLow Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (0.0%) and iron (0.0%) 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: 0.0% + Iron: 0.0% + Magnesium: 90.0%✓ Mass: 0.8x Earth (terrestrial range)

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
