An asteroid the size of two football fields is set to pass by Earth today.
The giant asteroid should be at its closest to Earth around 3:20 p.m. Eastern time.
The giant space rock will zip by our planet this afternoon at a speed of around 22-thousand miles an hour. NASA says the asteroid, dubbed 501647, will come within 1.9 million miles of Earth. Scientists say that’s a close fly by because any object that makes it within about 4.5 million miles is considered “potentially hazardous.” A much smaller asteroid will also fly by today but it won’t get as close. Only about 3.5 million miles from us. Carmen Roberts. Fox News.
