A huge asteroid measuring six football fields will make a close approach to Earth on April 19, NASA said.
But there is no possibility for the asteroid to collide with the Earth as it will pass about 1.1 million miles (1.8 million kilometers from the planet, about 4.6 times farther away from the moon, the U.S. space agency said.
The asteroid will approach the Earth from the direction of the sun and will be visible in the night sky after April 19.
Discovered in 2014, the asteroid measures 650 meters in diameter it will be closest approach by any known asteroid of this size, or larger, since asteroid Toutatis (five-kilometer) which approached the Earth within about four lunar distances in September 2004, according to NASA.
Scientists and astronomers plan to observe the asteroid, known as 2014 JO25, with radar and telescopes to learn as much about it as possible.
