Drag and drop planets and comets around the Sun to create your own solar system. Learn more about stars, planets and comets with definitions and videos.
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.
About: PlanetMaker allows you to create and tweak your own planet using image textures, lighting, and more importantly, your imagination. More Information. Use of any images generated using PlanetMaker are free for your use in any medium.
Custom design a planetary system and study your creation with this interactive tool. Enter the names, sizes, eccentricities and semimajor axes of up to four planets and see how they orbit around the central star.
Explore and design your own solar system with this interactive simulation, observing gravitational forces and celestial body orbits.
