The asteroid, known as 216258 2006 WH1, is set to take its closest approach to Earth on December 20 – just days before Christmas. The 540-meter space rock is the same size as the World Trade Center and would cause significant damage and mass extinction. It is now believed that the asteroid invades the Earth at a speed of 43,200 km / h or 26 843.
The course of the asteroid may be further influenced by a natural phenomenon known as the Yarkovksay effect.
The effect occurs when the gentle power of sunlight blocks an asteroid in any way from its natural course.
Its effect on an asteroid was demonstrated in 2012 with a mastoid 1999RQ36.
Scientists, using the Yarkovksay effect, were able to determine the most accurate determination of the orbit of asteroids to date.
Asteroids larger than approximately 35 meters pose a threat to a city or city, which means that the WH1
The asteroid has not yet been measured on the Torio Impact Scale, but is likely to come out as a serious threat when and if added.
Removed version of the Turin scale was presented to the United Nations in 1995.

Ten of the rocks means a collision is certain, capable of causing a global climate catastrophe that could threaten the future of civilization as we know it, whether they collide by land or ocean.
Such events occur on average once every 100,000 years or less.
One on the scale corresponds to a routine and "normal" finding.
This "normal" terminology only appeared in 2005, when originally one of the scales meant "events that deserve close observation".
This led to an exaggerated reflection in the press, as single-scale asteroids were relatively common, so the terminology had to be changed to "normal" so as to avoid mass and panic stirring.  For these asteroids, calculations show that the likelihood of a collision is extremely unlikely, without cause for public attention or concern.
New telescopic observations will very likely lead to the reassignment of the initially classified as first level, which eventually will become Level one.
Organizations such as NASA and the European Space Agency (ESA) are closely watching NEOs passing near Earth.
NEO are all comets and asteroids whose orbits are approaching the Earth's path around the Sun.
NASA says, "NEO includes every asteroid, meteor or comet orbiting the Sun within 18,600,000 miles, 30 million miles from Earth." , more than 20,000 cosmic rocks are classified as NEOs.
