Life Detected Magnetic Field High Activity
Why is this a Rocky Terrestrial? Your planet is dominated by silicate (5.9%) and iron (24.0%) 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: 5.9% + Iron: 24.0% + Magnesium: 1.7% ✓ Mass: 2.2x Earth (terrestrial range)

Moon 1 stable 0.010% - 19.3 radii
Small and distant: a quiet, stable companion.
Moon 2 receding 0.79% - 84.0 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
