How NASA protects Earth from deep space asteroids


The Planetary Defense Coordination Office is working to keep us safe from hazards on a collision course with the planet.


NASA's Planetary Defense Coordination Office helps find and track near-Earth objects, such as asteroids, that may crash into Earth.

Those objects are characterised to determine parameters such as their orbit trajectory, size, shape, mass, composition and rotational dynamics so experts can determine the severity of the potential impact event.

An object on a collision course with Earth could be deflected or disrupted to mitigate its effects.
