Here's something to dwell on as you head to work next week: A small asteroid the size of a tour bus will make an extremely close pass by the Earth on Monday, but it poses no threat to the planet.
The asteroid will make its closest approach at 1:14 p.m. ET on June 27 and will pass just over 7,500 miles above Earth's surface, NASA officials say. At that particular moment, the asteroid — which scientists have named 2011 MD — will be sailing high off the coast of Antarctica, almost 2,000 miles (3,218 kilometers) south-southwest of South Africa.
According to the Minor Planet Center at the Smithsonian Astrophysical Observatory, Asteroid 2011 MD—a hunk of rock estimated to be anywhere from 25 to 55 feet wide–is going to buzz the Earth this Monday at a distance of less than 8,000 miles above the surface of the planet. It's a close call, one that puts the asteroid closer to the Earth than the global positioning satellites that orbit it. But don't start running into the underground bunker just yet: We'll be fine.
