Asteroids: NASA spots potentially hazardous rock approaching Earth

"Potentially Hazardous Asteroids (PHAs) are now defined based on parameters that measure the asteroid's potential to make threatening close approaches to the Earth", NASA said in a statement. Due to its size and unsafe orbit, the space rock has been labelled as a potentially hazardous asteroid.

NASA has warned that kilometer-sized asteroids can have catastrophic consequences if they collide with earth. The report quoted NASA saying it is bigger than the largest man-made structure in the world.

NASA's Center for Near-Earth Object Studies (CNEOS) has said that the incoming asteroid, dubbed 163373 (2002 PZ39), could intersect Earth's path on February 15 (Saturday) at 6:05 am (EST).

Potentially hazardous asteroids are 500ft (150m) across or larger and approach Earth's orbit from within 4.6 million miles (7.5 million km).

"Potentially Hazardous Asteroids (PHAs) are now defined based on parameters that measure the asteroid's potential to make threatening close approaches to the Earth", according to a NASA statement.

Asteroid PZ39 is estimated to measure somewhere between 1,443ft and 3248ft (440m to 990m) in diameter.

NASA has confirmed that an asteroid larger than the tallest man-made structure in the world is now travelling towards Earth at a speed of nearly 34,000 miles per hour.

The space agency said: "No one should be overly concerned about an Earth impact of an asteroid or comet". Since it traces an Earth-crossing orbit, the chances of a collision remain high every time it moves this way.

Currently, there is no known asteroid that is headed directly for Earth and that includes Asteroid PZ39.
