A peanut-shaped asteroid the size of the Gibraltar rock has become the largest asteroid to come this close to Earth since 2004.

The object passed close to our planet, zooming by at a distance of just over 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, was 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, 1.8 million km.

Scientists have estimated it is between 600m and 1400m wide.
