Asteroid threat is coming!
Asteroids are constantly hovering in space in the form of rocky pieces which are a threat to the Earth.
Sometimes very heavy asteroids come close to the earth and can cause destruction.
Sensing the danger of asteroids, NASA tracks them and issues alerts.
NASA's JPL has issued an alert for one such asteroid today.
Asteroid 1998 WB2 is going to come close to the Earth in the next few hours which is 470 feet big.
NASA has described its size as that of a building. Which can prove dangerous.
It is going to come closer to the Earth by 4,210,000 Kilometers.
The threat of such a heavy asteroid will continue to hover near the Earth for the next few hours. However, NASA has not yet released information about its collision.
