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.
