The asteroid, known as 216258 2006 WH1, is set to its closest approach to Earth on December 20, just days before Christmas. The 540 meter high space rock is the size of the World Trade Center and would cause significant damage and mass extinction.
The asteroid is currently raging at a speed of 43,200 km / h or 26,843 mph.
The course of the asteroid could be further influenced by the natural phenomenon known as the Yarkovksey effect.
The effect occurs when the gentle force of sunlight surrounds an asteroid on both paths of its natural course.
His influence on 2012 was demonstrated with the mastoid 1999RQ36 an asteroid.
Using the Yarkovksey effect, scientists were able to estimate the most accurate orbit orbit determination so far.
Asteroids over 35 meters in diameter pose a threat to a. This means that the 540 meter diameter of 21
The asteroid has not yet been measured on the Torio Impact Hazard Scale, but is expected to be 1. This is considered a serious threat if and when it is added.
In 1995, the United Nations was presented with a slimmed-down version of the Turin scale.

One ten on the scale means that a collision is safe that can lead to a global climate catastrophe that can threaten the future of civilization as we know it, whether it's land or sea collision.
Such events occur on average once every 100,000 years or less.
A one on the scale corresponds to a routine and a "normal" discovery.
This "normal" terminology only emerged in 2005, when a one on the scale initially meant "events requiring supervision".
This led to exaggerated press coverage, as asteroids of scale one were relatively common, so the terminology had to be changed to "normal". so as not to panic and attract attention.  For these asteroids, the calculations show that the likelihood of a collision is highly unlikely, without giving rise to attention or public concern level zero.
Organizations such as NASA and the European Space Agency (ESA) are closely monitoring the near-Earth NEOs.
NEOs are all comets and asteroids whose orbits approach Earth's path around the Sun.
NASA comments: "An NEO includes all asteroids, meteoroids, or comets orbiting the Sun within a 30 million km radius."
Of the 829,361 known asteroids and 3,592 known comets in the system, more than 20,000 are space rocks classified as NEO.
