Drag and drop planets and comets around the Sun in this fun and educational activity. Learn more about the components of a solar system, such as stars, planets and comets, and watch a video explanation.
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.
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.
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.
Track noteworthy space objects in your browser in a 3D simulation of the solar system.
A real-time, in-browser, interactive simulation of our solar system. Observe what the solar system will look like at any given point in time.
Create and explore your own solar system with this interactive simulation, observing orbits, velocities, and gravitational forces of celestial bodies.
