Rocky Terrestrial
Magnetic FieldHigh Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (34.2%) and iron (20.5%) 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: 34.2% + Iron: 20.5% + Magnesium: 13.7%✓ Mass: 4.2x Earth (terrestrial range)

Surface Characteristics
Rocky surface with impact craters, possible volcanic featuresMoons
Moon 1rings1.3% - 2.8 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 2receding2.0% - 30.2 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
+5 temperature: large moon stabilizes the axial tilt - steady seasons+4 chemistry: tidal pools cycle wet and dry - a boost for prebiotic chemistry
