Using orbital data provided by the Jet Propulsion Laboratory's Center for Near Earth Object Studies, this visualization presents the trajectories of 50 potentially hazardous asteroids. A slider bar controls the speed of the animation. Buttons hide or show the labels and the traced trajectories.

Sources of data and equations applied in the model:

1. Orbital elements
2. Orbital periods
3. Potentially Hazardous Asteroids
4. Orbital Mechanics: Theory and Applications
