The non profit Space Data Association, which tracks satellites for potential collisions, analyzed the asteroid projected path and determined no spacecraft would be in its way.

football field will pass nearer to Earth than any other known object of its size on Friday, giving scientists a rare opportunity for close up observations without launching a probe. EST/1924 GMT, the asteroid will pass about 17,200 miles (27,520 km) above the planet travelling at 8 miles (13 km) per second, bringing it nearer than the networks of television and weather satellites that ring the planet.
Currently, DA14 matches Earth year long orbit around the sun, but after Friday encounter its flight path will change, said astronomer Donald Yeomans, with NASA Jet Propulsion Laboratory in Pasadena, California.
For scientists, DA14 presents a rare, albeit short, opportunity to study an asteroid close up. In addition to trying to determine what minerals it contains, which is of potential commercial interest as well as scientific, astronomers want to learn more about the asteroid spin rate.

will perturb its orbit so that actually instead of having an orbital period of one year, it lose a couple of months, Yeomans said. Earth is going to put this one in an orbit that is considerably safer, he said.

Although Asteroid 2012 DA14 is the largest known object of its size to pass this close, scientists say there is no chance of an impact, this week or in the foreseeable future.
