This year, NASA released an updated map of potentially hazardous asteroids (PHA) that shows the orbital paths of 1,400 asteroids that NASA is keeping an eye on. They're asteroids of interest because of their size--at least 460 feet in diameter--and have orbits that pass close to Earth's.
The good news is that these PHA pose no imminent threat to Earth over the next 100 years, according to NASA. NASA is tracking these asteroids to refine their predictions about impact probabilities in an ongoing survey of the sky for near-Earth objects. Of the largest asteroids that are big enough to pose any risk to Earth, NASA says it has identified roughly 95 percent of them.
