Asteroid DA14 is going to pass within 18,000 miles of the Earth this coming Friday night, Feb. 15 around 7:30.

It’s about 150 feet in diameter — half the size of football field — and weighs 18,000 metric tons.

If it hit the atmosphere it would explode with with the force of a small atomic bomb.

If you have a telescope, it’s possible to track it. It’ll resemble a faint eighth-magnitude star traveling along a path in the evening Northeast sky.
