Planetary simulators

Welcome to Planetary Simulators A game where you begin as a small asteroid and grow into something greater. Absorb smaller asteroids and materials like iron to gain mass and evolve over time. Start as an asteroid, then become a dwarf planet, planet, gas giant, brown dwarf, red dwarf, or anything you choose. Be careful—if you're too small, you can’t hold gas. Your atmosphere will leak away, just like in real life. Grow bigger to keep it and become more powerful. Create your path, evolve, and become something extraordinary in the universe.
