A new asteroid survey has revealed fewer asteroids near Earth.

NASA estimates that around 4,700 asteroids are close enough and big enough to pose a risk to Earth.

A humongous asteroid is hurtling towards Earth as we speak.

The Asteroid is due to fly past Earth on Feb. 15.

The giant asteroid Vesta is seen in an image taken from the NASA Dawn spacecraft about 3,200 miles above the surface on July 24, 2011.
