200 meters long much more powerful than a nuclear bomb named as 2017 XC62.
As per NASA’s asteroid tracker, a massive asteroid the size of the Washington Monument will pass close to Earth in end of January.
While a collision with an asteroid of this magnitude is rare, the consequences might be significantly worse than most nuclear explosions.
This asteroid, known as 2017 XC62, is predicted to be between 100 to 200 meters in size and is scheduled to travel by the Earth on January 24
at a speed of roughly 4.35 kilometers per second.
However, it is doubtful to collide because it is expected to fly nearly 6 million kilometers above the Earth’s surface.
The distance between the Earth and the Moon, by comparison, is approximately 384,500 kilometers.
THE LAST Time a huge asteroid hit the globe was in 2013, when a 16meter asteroid destroyed in the sky above Russia.
However, the LAST massive asteroid impact occurred in 1908 over Russia’s Podkamennaya Tunguska Stream, in what is now known as the
Tunguska disaster.
When the asteroid burst in the air many kilometers above the place, it generated a powerful 12 megaton explosion that wreaked havoc for
thousands of kilometers.
That would make it almost 800 times more powerful than “Little Boy,” a 15kiloton atomic bomb dropped over Hiroshima during World War II, and 600 times more powerful than “Fat Man,” a 20-kiloton bomb launched over Nagasaki three days later.
The Tunguska incident is the biggest in recorded history (though greater ancient events occurred) and one of the greatest explosions ever
recorded significantly more powerful than numerous nuclear weapons.
Fortunately, 2017 XC62 offers no immediate threat to Earth, and NASA is certain that our planet will be safe from an asteroid strike for the
next century.
