Solar System SimulatorReal planet orbits in your browser.
The planets start where they were on 1 January 2000 and move under real gravity, with published orbital data.
Speed time up, follow a planet, add your own worlds and export the motion as a clip.

THREE SIMPLE STEPS
How to use the Solar system simulator
Change the speed
Set how many days pass per second, follow a planet with the camera and turn on long trails.
Add worlds and export
Drop a new planet or throw an asteroid through the system, then export a vertical, square or wide video.

Solar system simulator FAQ
Is the solar system simulator accurate?
The planets use published orbital elements and masses and move under the gravity of the Sun and each other, so Earth needs 365.25 days per orbit and Mars 687. Orbits are drawn flat in the plane of Earth's orbit.
Can I see the outer planets?
Yes. Choose Outer solar system to watch Jupiter, Saturn, Uranus and Neptune; time runs much faster there because Neptune needs almost 165 years for one orbit.
Can I add my own planet?
Yes. Switch to Add, pick a planet and click to place it on a circular orbit, or drag to throw it. Make it heavy enough and watch it disturb its neighbours.
Is it free?
Yes, completely free with no sign-up and no watermark on exported videos. Everything runs in your browser.
