Life DetectedMagnetic FieldModerate Activity
Why is this a Earth Like?Your planet has a balanced composition with all CHNOPS elements, proper mass (1.5x 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: 1.5x Earth (0.5-2.0x range)✓ Temperature: 283K (250-320K range)✓ Magnetic field present✓ Distance: 0.61 AU (habitable zone)

Contributing Factors
water100
Abundant liquid water at surface temperature
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry100
All CHNOPS elements present - building blocks of life (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 1rings0.026% - 1.8 radii

Inside the Roche limit (2.80 planet radii): torn apart into a ring system.

Moon 2stable0.043% - 30.2 radii

Small and distant: a quiet, stable companion.

Moon 3receding1.8% - 70.0 radii

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