Asteroid 2012 DA14's Near Miss

Didn't realized that such a thing will be occurring until I found this gif doodle appearing on Google's homepage.

Apparently, on 23rd February 2012, a near-Earth asteroid with an estimated diameter of 50 meters (160 ft) and an estimated mass of 190,000 metric tons was discovered and named "2012 DA₁₄".

And calculations were made showing that this asteroid would pass by Earth just 27,700 km from its surface...Today on the 15th February 2013. What's more, this is probably the closest approach known for an object (of this size) to fly-by Earth.
