The impressive asteroid, known as the Asteroid 2011 HP, is speeding in the Earth's direction at speeds of 8.43 km per second. Second or 18.857.4mph (30.348kmh). NASA expects the asteroid to make a so-called Earth Close Approach, which means that its orbit will bring the rock incredibly close to Earth. The US spacecraft has predicted that the asteroid will scrape around at about 10am. 11.48 UK or at. 6.48 am Eastern Time. The incredible flyby will mark the second time the space rocks near miss the earth since its discovery in 2011.
Asteroid HP is a space tribal of the Apollo type belonging to a group of rocky objects named after Asteroid 1862 Apollo.  First discovered on April 13, 201
As a result of its frequent approaches, NASA has called the asteroid a Near Earth object or NEO. 19659003] NEO & # 39; are all comets and asteroids on paths that occasionally cut into Earth's orbit.

NASA explained: "As they encircle the sun, near the objects of the earth, the earth may occasionally be approached.
" Note that a "close" passage astronomically can be very far away in human terms: millions or even tens of thousands of kilometers. "
And if that thought wasn't scary enough, the space rock could be twi ce as high as the great pyramid of Giza.
NASA's asteroid trackers at the Jet Propulsion Laboratory (JPL) estimated Asteroid HP measures somewhere between 328ft to 754.6ft (100m to 230m) across.

An asteroid in the upper end of the estimate is as tall as the iconic Golden Gate suspension bridge in San Francisco, USA.
At the bottom end of the estimate, the asteroid is still incredibly formidable and comparable in size to the Big Ben's clock tower in London.
Any object it great, could be s Torture enough to wipe out a big city if it hit a populated area.  Then is there any concern that the asteroid comes within striking distance tomorrow?

Fortunately, its closest, the asteroid will miss the earth from a dist ance of about 2.92 million miles (4.7 million km ).
The distance corresponds to approx. 12.26 times the distance to the moon.
And after the room's stone swings past the Earth's small corner of space, the rock will not make another flight city until May 17, 2027.
Then, the NASA expects the asteroid for the next visit the earth on May 6, 2035.
