Planeturex

Design your own planet and test if life can survive under real physical constraints. Adjust orbit, atmosphere, and planetary structure while the system continuously recalculates temperature, radiation, and water stability. Every change produces immediate consequences, forcing you to rethink and refine your design. Explore how small parameter shifts can trigger extreme outcomes like freezing or runaway greenhouse effects. Run long-term simulations to see whether your world remains stable over time. Take on constrained challenges that push you to master the system rather than guess outcomes. Compare multiple planet builds to understand what truly makes a world habitable. Iterate endlessly and discover new solutions through experimentation.
