Solar System 3D

It is a free interactive 3D model of the Solar System. You can fly around the Sun and all eight planets, see where the planets really are today, and read facts about each one.

Yes — it is 100% free with no signup. It runs in your browser on phones, tablets and computers.

Yes, approximately. When the page opens, the planets are placed where they really are today, calculated from their orbits. Press the Today button any time to return to the real positions.

No. In space the distances are so large that a true-scale model would show the planets as tiny dots, so the planets are drawn bigger than life. Compact mode keeps the orbits close, and Realistic mode spreads them out in proportion to their real distances.

Drag to rotate the view, scroll or pinch to zoom, and click any planet or use the planet bar at the bottom to fly to it. The arrow keys move to the previous or next planet.

Yes. Use the speed menu to run time from 1 day per second up to 1,000 days per second and watch the planets orbit. The date counter shows the simulated date.

Press Gesture control and allow your camera. Show 1 finger for Mercury, 2 for Venus, 3 for Earth, 4 for Mars, 5 for Jupiter, a thumbs down for Saturn, the rock sign for Uranus and the shaka sign for Neptune. A thumb up or fist shows the Sun, and no hand returns to the full view.

No. The video is processed on your own device only and is never recorded, saved or sent anywhere. The hand-tracking model is loaded from a public CDN only when you turn gestures on.

Your browser needs HTTPS and permission to use the camera. Check that no other app is using the camera, allow access when asked, and use good light. If it still fails, you can use the mouse, touch or keyboard instead.

The Moon, Jupiter’s four large moons (Io, Europa, Ganymede and Callisto), Saturn’s moon Titan, Saturn’s rings, a faint ring around Uranus and the asteroid belt between Mars and Jupiter. You can switch moons, asteroids, orbits and labels on or off.

Diameter, distance from the Sun, day length, year length, number of moons, temperature and gravity, plus a short description and a fun fact.

Yes. Use the camera button to save a screenshot of the current view, or the fullscreen button for a bigger view.

Yes. You can drag with one finger, pinch to zoom and tap a planet. A phone must support WebGL, which almost all modern phones do. It works best on a recent phone or a computer.

The planet surfaces are generated by the page itself, so no image files are downloaded. They are artistic and not real photographs.
