According to the International Business Times, quoting CNEOS, "potentially hazardous asteroids" are defined by the parameters that measure an asteroid's potential to make threateningly close approaches to Earth. The asteroid is likely to come near the approachable range from the Earth around 11 am GMT on February 15.
The space scientists at the NASA draw reference of a 10 kilometres wide rock striking the Earth 86 years ago which resulted in the extinction of the Dinosaurs as well as two-thirds of life on our planet to compare the magnanimity of the complications the PZ39 can bring with it. This potential doomsday space rock named, '163373 (2002 PZ39)' is now screeching across space at a mindblowing speed of 35,500 miles per hour, and if it hits the Earth, the blue planet will face the ultimate catastrophe after the asteroid hit that wiped out dinosaurs. CNEOS has identified 2002 PZ39 as an Apollo asteroid. An asteroid this big in dimension holds the potential to destroy a whole continent, let alone a country or a city.
DON'T MISSWhat happens after death?
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.
However, NASA has said the risk of dying from an asteroid impact in the foreseeable future is very slim.

The space agency said: "No one should be overly concerned about an Earth impact of an asteroid or comet".
At its closest, the space rock will approach Earth from about 0.03860 astronomical units. However, extremely lucky for us, it will be a distance of around 3.6 million miles away - about 15 times the distance of our moon.
In other words, NASA expects the rock to safely miss us by more than 3.58 million miles (5.77 million km).
