Astronomers have warned that a “Statue of Liberty” sized asteroid may hit Earth in October 2017. Scientists estimated Asteroid 2012 TC4 is around 40-metres wide and could cause even more chaos than one which hospitalised more than 1,200 people when it exploded over Russia in February 2013. However, Detlef Koschny, head of the near-earth object segment at the European Space Agency (ESA) said that there was a one in a million chance that it could hit Earth.
