Earth’s latest close encounter with an asteroid

Come Monday, an asteroid, the 2011MD, will pass quite close to Earth. How close? It’ll be closer to Earth than the orbits of GPS satellites, and will be so strongly deflected by Earth’s gravity that it’ll almost go back the way it came!

Here are some amazing simulations of the asteroid’s flyby – these are a must watch!
