Don’t worry, everyone. There is no need to call Bruce Willis in to save the world. Asteroid 2011 MD will make a very close pass to the Earth today at about 1:00 PM EST, coming within 7,500 miles above the planet (specifically, above Antarctica). While this is close enough to pass beneath some of Earth’s satellites, there is “no chance” that 2011 MD will enter our atmosphere and hit the Earth, according to scientists at NASA’s Jet Propulsion Laboratory. The diameter of MD 2011 is estimated to be rather small – between 29 to 98 feet – so IF there was a chance it might enter our atmosphere, it would most likely break apart and burn up upon entry. If you are clever enough to be able to track moving objects with a medium-sized telescope, you might be able to spot 2011 MD in the sky.
So don’t worry about rushing down to your basements and preparing for the worst. Space.com has the full scoop, as well as a trajectory map of the asteroid’s path.
