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)
Habitability ScoreMarginal
Contributing Factors
water20
Very dry - minimal water
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 Chemistry80
Core organic elements (CHNO) present
atmosphere40
Nitrogen-oxygen atmosphere - breathable and protective (partially stripped by slow rotation)
temperature100
Optimal temperature range for liquid water and life
magnetic Field100
Magnetic field provides radiation protection

Surface Characteristics
Rocky surface with continents, oceans, and active plate tectonics. Diverse biomes if life present.Moons
Moon 1rings0.10% - 2.8 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 2receding0.21% - 7.5 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
