Why is this a Rocky Terrestrial?Your planet is dominated by silicate (12.9%) and iron (19.4%) 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.
Classification Criteria:
✓ Silicon: 12.9% + Iron: 19.4% + Magnesium: 3.2%✓ Mass: 1.3x Earth (terrestrial range)

Contributing Factors
water50
Limited water content
geology90
Active geology recycles nutrients and drives carbon cycle
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry50
Carbon and hydrogen present - organic chemistry possible
atmosphere28
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)
temperature70
Challenging but potentially habitable temperature
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1receding0.17% - 6.8 radii

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).

Tidal braking locked the planet to its moon: one face forever moonward.

Moon 2rings0.22% - 1.8 radii

Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
