Asteroid Capture uses Newton's Laws of Universal Gravitation to simulate the motions of the Earth and an asteroid in 3D. Try to capture the asteroid in Earth orbit by adjusting its starting position and direction, initial velocity, and mass. Once set in motion, the movements of both bodies are the results of their interaction with each other. Whether the asteroid collides with the Earth, orbits the Earth, or flies off into space is determined by the initial conditions and the laws of physics.
To help get you started, some suggested scenarios are provided, including elliptic orbit, circular orbit, geostationary orbit, polar orbit, low Earth orbit, hyperbolic trajectory, and mass extinction event.
