ASTEROID 2012 TC4 CLOSE FLY-BY

On October 11-12, 2017, a tiny near-Earth object (NEO) swept very close to Earth. Designated with the name 2012 TC4, this 15-30 meter wide asteroid (comparable to the 2013 Chelyabinsk meteor) flew by nearEarth at around 11% the Earth-Moon distance. Specifically, it made its close encounter with Earth at about 44,000 kilometers above Antarctica at 9:42AM, UAE Local Time. Fortunately, it did not hit Earth thanks to its gravity deflecting the asteroid’s trajectory away from Earth around its orbit.
