Ukrainian astronomers have discovered a large asteroid heading for Earth which could strike our planet on 26 August 2032, impacting with a force 50 times greater than the biggest ever nuclear bomb.
Its existence has been verified by teams around the world, in at least 27 distinct observations over the course of the past week, and Nasa has been forced to issue an earth impact risk summary as part of its Near Earth Object Program.
The 1,300 foot (400 metre) wide asteroid has been named 2013 TV135. There is a 1 in 63,000 chance of the asteroid striking earth – enough for it to be added to the Torino scale which measures the risk of all objects which could reach Earth in the next 100 years.
