Earth safe from asteroid for 100 years: NASA

First detected in 2004, Apophis is now officially off NASA's asteroid “risk list”

Whew, now here's some good cosmic news: NASA has given Earth the all clear for the next century from a particularly menacing asteroid. The space agency announced this week that new telescope observations have ruled out any chance of Apophis smacking Earth in 2068. That’s the same 1,100-foot (340-meter) space rock that was supposed to come frighteningly close in 2029 and again in 2036. NASA ruled out any chance of a strike during those two close approaches a while ago. But a potential 2068 collision still loomed.
