An asteroid the size of the Gibraltar rock has beee the largest asteroid to come this close to Earth since 2004.

On Wednesday afternoon, the object passed close to our planet, zooming by at a distance of just over a million miles (1.8 million km), but with no chance of impact, according to Nasa scientists.

Smaller asteroids regularly come closer than this , but 2014 J025, discovered in May 2014, will be the largest asteroid to come this close to the planet since 2004, flying by at only about 4.6 times the distance from the Earth to the Moon, 1.1 million miles (1.8 million km).
