Free simulations
Explore Earth, gravity, planetary motion and impact physics.
All simulations ↗FEATURED SIMULATION
Spacetime explorer
Explore the solar system in a 3D grid. Select a planet, move around it and adjust the orbit speed.
Sun-centered view. Drag to rotate.
Drag to rotate. Tap a planet to follow it. Use + and − to zoom. On phones, drag sideways; swipe up or down to scroll the page.
The grid illustrates gravity. Planet sizes, distances and bending are exaggerated for visibility.
