An Asteroid Will Pass Earth In One Of Closest Ever Encounters

An asteroid the size of a delivery truck will whip past Earth on Thursday night, one of the closest such encounters ever recorded. NASA insists it will be a near miss with no chance of the asteroid hitting Earth. This newly discovered asteroid will zoom 3,600 kilometers above the southern tip of South America.  That’s 10 times closer than the bevy of communication satellites circling overhead.  Even if the space rock came a lot closer, scientists said most of it would burn up in the atmosphere, with some of the bigger pieces possibly falling as meteorites. The asteroid’s path drastically will be altered by Earth’s gravity once it zips by.  Instead of circling the sun every 359 days, it will move into an oval orbit lasting 425 days, according to NASA.
