Bus Sized Asteroid
Bus Sized Asteroid. Astronomers got a treat yesterday when an asteroid roughly the size of a bus passed within 7,500 miles of Earth—closer than many satellites. The space rock, named 2011 MD, was over the south Atlantic near Antarctica at the time of its closest approach, reports the Christian Science Monitor. The asteroid was only spotted a few days ago, but experts say it was too small to have survived entering Earth's atmosphere even if it was on a path to score a direct hit.
