Your planet builds its crust from exotic minerals (29.5% calcium/titanium/aluminum-family rock formers) instead of the silicate-iron recipe every standard rocky world uses.
Exotic terrestrials are temperate solid worlds whose geology skipped the silicate playbook - carbonate plains, titanium-gray mesas, alkali flats. They can hold air, water ingredients, and real habitability, but with no silicate continents or iron core they are their own class, not earth-likes.
Classification Criteria:
✓ Exotic rock formers: 29.5% (>=12% Ca/Ti/Al/K/Ni/U)✓ Standard rock: 4.3% (<15% - silicate rules never claimed it)✓ Temperature: 332K (240-380K temperate band)✓ Air + water ingredients: 39.6% O+H (>=15%) with an atmosphere

Contributing Factors
water78
Abundant water (low gravity lets water escape to space)
geology90
Active geology recycles nutrients and drives carbon cycle
rotation30
Very slow rotation - extreme temperature swings between eternal day and night sides
Organic Chemistry100
All CHNOPS elements present - building blocks of life (tidal pools cycle wet and dry - a boost for prebiotic chemistry) — but the ground itself is radioactive, and no magnetic field shields a world from its own crust
atmosphere40
Atmosphere present but composition not ideal for life
temperature70
Challenging but potentially habitable temperature
magnetic Field100
Magnetic field provides radiation protection

Surface Characteristics
Pale mineral plains — carbonate flats, chalk mesas, and crusts no silicate world can build
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 2rings0.00032% - 3.6 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 3stable0.025% - 12.6 radii
Small and distant: a quiet, stable companion.
Moon 4merged0.56% - 1.2 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.

Habitability
✓ Conditions could support lifeThis planet’s modelled conditions could support biological processes: stable temperatures, liquid water and the chemistry life as we know it needs. That makes life possible, not present.
