A diverse world of floating islands, lush jungles, sprawling savannas, and tall mountains. Tirra is home to a spacefaring race, called Tirrans. They have just discovered the seafaring species on their neighboring planet, Oceari.
Why is this a Earth Like?Your planet has a balanced composition with all CHNOPS elements, proper mass (0.9x Earth), and sits in the habitable zone at 2.63 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: 0.9x Earth (0.5-2.0x range)✓ Temperature: 272K (250-320K range)✓ Magnetic field present✓ Distance: 2.63 AU (habitable zone)
