Asteroid 2011 SE58 (2011 means it was found in 2011 - this year) is very close to the earth and on a collision course with the earth. If it impacts, it will be within the next 24-48 hours. It also has many smaller asteroids - would be meteorites - traveling with it.
Curently president obama is in an underground bunker in Colorado and many world leaders are in "recess" from the UN from the next few days.

Even if the asteroid does not hit the earth directly, there have been many fireballs that have hit the earth in the last 48 hours and one person has been killed in Argentina from an explosion witnesses claim was caused by a fireball: http://www.hindustantimes.com/Argentine-blast-kills-woman-injures-9/Article1-750594.aspx
