The simulator uses a simplified gravitational model based on Newton's law. An object is launched from a set distance with an initial tangential velocity. The gravitational pull from a central mass then alters its trajectory in real time.
The orbiting object is shown in blue for a stable orbit, green when it escapes the gravitational pull, and red if it crashes into the central mass.
Use the sliders to adjust the central mass, initial distance, and tangential velocity. Any change automatically restarts the simulation to reflect the new settings.
