Lee Sawyer, the Charles and Newellyn Spreull Professor of Physics at Louisiana Tech University, and NASA are predicting that an asteroid, measuring approximately 150 feet in diameter and weighing approximately 130,000 metric tons, will fly closer to Earth on Friday than any object of its size ever has before.

Asteroid 2012-DA14 will pass within 17,200 miles of the Earth’s surface, which is closer than the orbit of most weather and communications satellites and is about one-tenth the distance between Earth and the Moon.

However, Sawyer says we have nothing to fear.
