The asteroid 2012 DA14 will fly extremely close to Earth on Friday, Feb. 15, but poses no risk of impacting our planet.  It may, however, be visible in backyard telescopes if you know when and where to look, but will be a stargazing challenge, NASA says.

Discovered last year, asteroid 2012 DA14 is about half the size of a football field and will approach within 17,200 miles (27,680 kilometers) of Earth when it flies by during its close encounter.

Update, Saturday, Feb. 16: Asteroid 2012 DA14 has completed its flyby of Earth and is now headed away from our planet to continue along its orbit around the sun. See our complete coverage of the event below.
