NASA's Planetary Defense Coordination Office

The NASA office concerned with potentially hazardous objects (PHOs), which are defined as the asteroids or comets whose orbits get within 0.05 AU (an astronomical unit, the average distance between the Earth and the Sun) of Earth's orbit and are above a certain size. They are responsible for the early detection of PHOs, tracking and characterizing PHOs, providing timely and accurate communications about PHOs and coordinating the US government planning for a response in the case of an actual impact threat.
