NASA says there is no chance of asteroid 2012 DA14 hitting earth. However, there is a remote possibility that it could collide with one of more than 100 telecommunication and weather satellites in fixed orbits above the earth. It is due to fly by around noon MST. You can watch the flyby via feeds from NASA at http://www.ustream.tv/nasajpl2 and hear commentary at http://www.nasa.gov/multimedia/nasatv/index.html
