Asteroid 2008 OS7 is heading towards Earth. He will just miss us, but will come back in 2032.

The asteroid could be as long as the Empire State Building in New York City or the Commerzbank Tower in Frankfurt am Main. Three much smaller asteroids will also fly harmlessly past Earth on Friday, measuring no more than 10 meters in diameter, and two more on Saturday. On Sunday, an asteroid about half the size of 2008 0S7 will fly past Earth at a distance of 7.3 million kilometers.
