Large Asteroid to Fly by Earth Wednesday
An asteroid just over two kilometers wide will pass close to earth Wednesday. But scientists with the U.S. space agency, NASA, say the object poses no threat to the planet.The asteroid is known as 1998 OR2, named for the year it was first discovered. It will safely pass at a distance of 6.3 million kilometers from Earth — about 16 times the distance between the Earth and the moon.NASA scientists say by astronomical standards, that distance still classifies the asteroid as a “near-earth” object and worth watching. The space agency considers objects that pass within 48 million kilometers of our planet a “near-earth” object. NASA maintains a planetary defense coordination office that keeps track of such objects and plots their courses through space. In an interview posted on the space agency’s website,…
