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: 282K (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

rotation100

Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution

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
