This 2D visual model illustrates the scale of the sun and planets in our solar system, and their current distance from each other.
Online 3D simulation of the Solar System and night sky in real-time - the Sun, planets, dwarf planets, comets, stars and constellations.
This is an interactive model of the solar system that is quite, but not entirely, realistic. The vast distances and differences in space and time that are present in the real solar system can make observation boring or intimidating.
Build your own solar system with planets and comets! Learn more about solar system with our interactive simulation.
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.
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.
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.
