Asteroid 2003 QQ47

Lunar & PlanetaryAsteroid 2003 QQ47 is being closely monitored by British astronomers after they discovered it may pass uncomfortably close to Earth on March 21, 2014. Judging from the size of the asteroid, scientists predict it could have the same impact as 20 million Hiroshima-size atomic bombs. The good news is that astronomers are unsure of their calculations.
