Your planet has a balanced composition with all CHNOPS elements, proper mass (2.7x Earth), and sits in the habitable zone at 2.29 AU.
Earth-like planets have the perfect combination of composition, temperature, mass, and magnetic field to potentially support complex life as we know it.
Classification Criteria:
✓ All CHNOPS elements present (C, H, N, O, P, S)✓ Mass: 2.7x Earth (0.5-2.0x range)✓ Temperature: 290K (250-320K range)✓ Magnetic field present✓ Distance: 2.29 AU (habitable zone)

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 Chemistry100
All CHNOPS elements present - building blocks of life (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere40
Nitrogen-oxygen atmosphere - breathable and protective (partially stripped by slow rotation)
temperature100
Optimal temperature range for liquid water and life (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection

Surface Characteristics
Rocky surface with continents, oceans, and active plate tectonics. Diverse biomes if life present.
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.

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.
