An asteroid about the size of a 15-story building will “narrowly” streak by the planet Earth on Friday, February 15. The 2012 DA14 asteroid measures 150 feet (46 meters) in diameter, and its closest point to Earth will come at approximately 2:25 p.m. EST (1925 GMT) Friday, when it will be roughly 17,200 miles (27,681 kilometers) away. Space experts agree the asteroid is not a threat to Earth.
“This flyby will provide a unique opportunity for researchers to study a near-Earth object up close,” NASA said on its website.
