Drag and drop planets and comets around the Sun to create your own solar system. Learn more about stars, planets and comets with definitions and videos.
Create your own solar system with this orbit simulator. Choose the number and properties of planets, stars, or other bodies, and watch them interact with gravitational force.
Make your own solar system by dragging bodies and the V symbol (V for velocity) or by typing into the initial settings table in the upper-left corner of the simulation. Distances, masses, and times are in arbitrary units. Invent your own! Keep masses less than a few thousand or risk strange results.
Create your own solar system and watch it evolve with this interactive simulation. Customize the star temperature, planet types, rings, moons, and more, and see how they affect the habitability and evolution of life.
In this solar system simulator players can create their own solar systems with multiple stars and planets. You can also add comets and asteroids to your simulation. How does this work?
This interactive online solar system creator allows you to dream up planets, moons, sun, and more. To create your solar system, use the “Add” button at the top to add new planets. Change the characteristics of each planet by using the buttons below the solar system model.
