An asteroid as large as five football fields will zoom by Earth tonight, and you can watch the close approach live from the comfort of your home.

The near-Earth asteroid 2003 DZ15 will come within 2.2 million miles (3.5 million kilometers) of our planet  — about nine times farther than the distance between Earth and the moon — tonight (July 29) at 8:37 p.m. EDT (0037 GMT on July 30). There is no chance that 2003 DZ15 will strike Earth on this pass, scientists say.
