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.
