An asteroid feared to be on a collision course with Earth no longer poses a significant risk to the planet.
Experts previously said there was up to a one in 500 chance of the space rock, which is as wide as two football pitches, crashing into Earth in February 2040.
However, when astronomers made further observations to better predict the asteroid's course, they found it would pass no closer than 550,000 miles to the planet - a distance equivalent to more than two trips to the moon.
