This app simulates the trajectories of nearby asteroids that are potentially dangerous to Earth. You can watch in real time where they are, were, or will be at any given time.
All trajectories of the asteroids shown here are based on real data from NASA's Near Earth Object Program: http://neo.jpl.nasa.gov/
Besides the asteroids, you can also watch the following planets: - Mercury - Venus - Earth - Mars - Jupiter
Get the full version to watch over 1000 near-earth asteroids. The full version includes all asteroids known by NASA whose trajectory comes closer than 0.02 AU to Earth's orbit, and which size is larger than 50m in diameter.
NOTE: Asteroid trajectories are inherently unstable, so they are difficult to predict far into the future. The trajectories calculated by this app cannot be considered 100% accurate, particularly for dates far into the future.
