What is a Potentially Hazardous Asteroid?
A Potentially Hazardous Asteroid (PHA) is a near-Earth object larger than ~140 m that can pass within 0.05 AU (about 19.5 lunar distances) of Earth's orbit. The label reflects size and orbit geometry — it does not mean an impact is expected. NASA's CNEOS continuously refines each PHA's trajectory.
