Armageddon 2040: Nasa identifies new asteroid threat

It is 460ft wide and soaring through space - on a possible collision course with Earth.
Nasa has identified a new asteroid threat to our planet and calculated that it could potentially impact on February 5th 2040
The 2011 AG5 has already attracted the concern of the UN Action Team on near-Earth objects, which has begun discussing ways to divert it.
They have put the odds of it hitting us at one in 625, though that could change nearer the time.
Were the rock to land on a city it could cause millions of deaths, although mankind would live through it. The asteroid which wiped out the dinosaurs 65 million years ago was nine miles wide, compared to 460ft for the 2011 AG5. Able to observe it for half its orbit.
But between 2013 and 2016 they will be able to monitor from the ground and will make a more detailed assessment.
In 2023 the rock will make a ‘keyhole pass’ of Earth, which is an area it passes through on the orbit before it would hit Earth.
According to NASA’s Jet Propulsion Lab, this will will be within a mere 0.02 astronomical units of our planet, or 1.86 million miles.
