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 or 4 bodies, and then see them orbit each other.
This simulation will allow students to build their own solar system of a sun, planets and moons, and watch their paths as they move about one another. 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.
New theory could disprove what we know about solar system's history
It was first proposed in 2011 that a fifth giant gas planet orbited the sun, but it is only now that experts have proposed how it was pushed out. An illustration of the modern solar system is shown above
