Not just these, NASA also relies on a space-based telescope, which is called NEOWISE for finding, tracking, and characterizing asteroids, and identifying those that may pose a hazard to Earth.

Whenever a Near-Earth Object (NEO) approaches within 4.6 mn miles or 7.5 mn km that is larger than about 150 meters, NASA issues a warning and marks it as a PHA.
