Rocky Terrestrial
Magnetic FieldModerate Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (50.0%) 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: 50.0% + Iron: 0.0% + Magnesium: 0.0%✓ Mass: 1.0x Earth (terrestrial range)

Surface Characteristics
Rocky surface with impact craters, possible volcanic featuresMoons
Moon 1rings1.6% - 2.2 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 2merged0.35% - 25.0 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 3receding0.35% - 17.6 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
