Rocky Terrestrial
Magnetic FieldModerate Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (17.9%) and iron (42.9%) 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: 17.9% + Iron: 42.9% + Magnesium: 10.7%✓ Mass: 0.9x Earth (terrestrial range)

Moon 1rings0.00079% - 1.5 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 2receding0.22% - 11.4 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
