Build your own solar system with planets and comets! Learn more about solar system with our interactive simulation.

Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.

Start by creating a simple planet and make it grow. Each planet can be a rock planet, a gas planet, or a star planet. Once you have your solar center, you can include new planets in orbit with satellites, turn them into black holes, level them up and much more.

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?

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.

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.

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 …

Explore and design your own solar system with this interactive simulation, observing gravitational forces and celestial body orbits.

This fun game allows students to create and print their own solar systems. They can specify planets, planet names, planet sizes, planet order, and whether or not planets have rings or moons.
