NASA says a large asteroid will fly by Earth on Feb. 15

Asteroid O2 PZ 39 will approach Earth on a Saturday, traveling at nearly 50,500 kilometers per hour. It has a diameter between 440 and 990 meters. If an asteroid larger than 20.5 meters but smaller than a kilometer hits Earth, it could cause local damage. Larger asteroids could have worldwide effects. Most asteroids orbit between Jupiter and Mars, posing little threat to Earth, but O2 PZ 39 is an exception. NASA classifies it as a near-Earth object, estimating it will miss Earth by 15.2 lunar distances or 5.8 million kilometers at 11:00 PM on February 15th.
