Why is this a Earth Like?Your planet has a balanced composition with all CHNOPS elements, proper mass (1.9x Earth), and sits in the habitable zone at 0.61 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: 1.9x Earth (0.5-2.0x range)✓ Temperature: 283K (250-320K range)✓ Magnetic field present✓ Distance: 0.61 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 Chemistry84
Core organic elements (CHNO) present (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

Small and distant: a quiet, stable companion.

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