SPACE: Nasa to Test Earth Defense System

Asteroid

NASA scientists are excited about the upcoming close flyby of a small asteroid and plan to use its upcoming October close approach to Earth as an opportunity not only for science, but to test NASA’s network of observatories and scientists who work with planetary defense.

The target of all this attention is asteroid 2012 TC4 — a small asteroid estimated to be between 30 and 100 feet (10 and 30 meters) in size. On Oct. 12, TC4 will safely fly past Earth. Even though scientists cannot yet predict exactly how close it will approach, they are certain it will come no closer than 4,200 miles (6,800 kilometers) from the surface of Earth. The asteroid has been out of range of telescopes since 2012.
