Asteroid to make close approach to Earth next week
Space.com: An asteroid half the size of a football field will make a close approach to Earth next week, but poses no threat of crashing into our planet, NASA officials say.
Asteroid 2012 DA14’s close encounter is a record-breaking celestial event, according to Don Yeomans, the head of NASA’s asteroid-tracking program. An object this large only passes this close to the Earth about once every 40 years, and likely only hits the planet once every 1,200 years, Yeomans says.
