An asteroid about half the size of a football field in diameter is set to pass closest to the Earth than ever before, NASA has revealed.

The asteroid, discovered by a group of Spanish astronomers in La Sagra observatory in southern Spain, is said to be coming from the south to the north.

Asteroid 2012 DA 14 is expected to get within 17,200 miles of the Earth's surface on February 15.

The large rock is thought to pass interior to the GPS satellites, and the space agency have reassured that there is no chance of the asteroid hitting the Earth, or a satellite.

NASA's Jet Propulsion Laboratory has posted more information about the asteroid:

NASA held a media teleconference to discuss the asteroid, saying that the event will create a unique opportunity for researchers to observe and learn more about them.

Although it is believed to be brighter than most asteroids, it is still not going to be visible to the naked eye, according to NASA.
