Why is this a Exotic Terrestrial?Your planet builds its crust from exotic minerals (40.5% 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: 40.5% (>=12% Ca/Ti/Al/K/Ni/U)✓ Standard rock: 12.2% (<15% - silicate rules never claimed it)✓ Temperature: 256K (240-380K temperate band)✓ Air + water ingredients: 40.5% O+H (>=15%) with an atmosphere
