Welcome to Solar System Builder! Here you can create your own solar system and watch it evolve. I've tried to be as scientifically accurate as possible in the simulation. Feel free to tell me if there's anything you want me to add that's not already included. Best viewed on fullscreen. Instructions: Set the star's temperature. Use the Choose Planet tab to insert up to 20 planets into your solar system. You can choose the type (small, Earth-sized, super-Earth, Jupiter, and Bigger sizes), but the color, rings, and moons of the planet will be completely randomized (though they can later be changed.) Using the box in the bottom left you can turn visualization of the habitable zone on and off, and super-Earth sized planets or smaller in the habitable zone have the potential to evolve life, but it will take a while to get started. Stars will eventually die - small stars have long lifespans into the tens of billions of years while big stars only last tens of millions, not enough time for life to emerge. Once your star dies, all the planets in the solar system will vanish. Use the up and down arrows to zoom. Press S to reveal the current seed. NOTE: Though I've tried to be as scientifically accurate as possible, I still need to make the sun and planets much larger than they would actually look in real life at this scale. Otherwise they would all be a pixel across. The orbits don't take millions of years either - but it would be impossible to simulate orbital times realistically without making the wait for life or star death agonizingly long. And, of course, the chance of life's evolution is completely made up, as we will probably never know the real number.
