Why is this a Earth Like?Your planet has a balanced composition with all CHNOPS elements, proper mass (1.0x Earth), and sits in the habitable zone at 1.00 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: 1.0x Earth (0.5-2.0x range)✓ Temperature: 278K (250-320K range)✓ Magnetic field present✓ Distance: 1.00 AU (habitable zone)

Contributing Factors
water50
Limited water content
geology90
Active geology recycles nutrients and drives carbon cycle
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere100
Nitrogen-oxygen atmosphere - breathable and protective
temperature100
Optimal temperature range for liquid water and life
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1receding1.3% - 63.0 radii

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

Moon 2merged0.89% - 77.7 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.
