Earth Like

Magnetic FieldModerate Activity
Why is this a Earth Like?Your planet has a balanced composition with all CHNOPS elements, proper mass (2.7x Earth), and sits in the habitable zone at 1.10 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: 2.7x Earth (0.5-2.0x range)✓ Temperature: 266K (250-320K range)✓ Magnetic field present✓ Distance: 1.10 AU (habitable zone)

Contributing Factors
water20
Very dry - minimal water
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere100
Nitrogen-oxygen atmosphere - breathable and protective
temperature70
Challenging but potentially habitable temperature
magnetic Field100
Magnetic field provides radiation protection

Surface views from three worlds: rocky ground under a ringed sky, a cloud deck, and a lit desert

New: Stand on Your World 🏔️

Every planet you build can now be seen from the ground. The terrain, the color of the sky, the weather and what hangs overhead are all read from the same numbers that shape the globe — so a thin-aired world gives you sunlit rock under a near-black sky crowded with stars, a runaway greenhouse seals you under an unbroken sulfur lid, and a gas giant leaves you in the cloud tops with nothing solid beneath you at all. If one of your moons wandered inside the Roche limit, what is left of it arcs overhead as rings.
