Rocky Terrestrial
Magnetic FieldLow Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (44.1%) and iron (14.7%) 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: 44.1% + Iron: 14.7% + Magnesium: 14.7%✓ Mass: 0.5x Earth (terrestrial range)

Rocky surface with impact craters, possible volcanic featuresMoons
Moon 1rings0.00010% - 2.8 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 2stable0.00089% - 18.5 radii
Small and distant: a quiet, stable companion.
Moon 3receding0.00010% - 67.4 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 4merged10% - 67.4 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 5stable0.00025% - 15.9 radii
Small and distant: a quiet, stable companion.
