Heidelberg - According to scientists from Plack Institute, Germany, a comet is predicted to destroy the Earth in the next quarter of a million years.
Study of the scientist named Coryn Bailey-Jones was argued that there are trillions of comets remnants of the formation of the solar system far beyond the orbit of the entrenched Neptune. Precisely in an area called the Oort Cloud.
Currently the comet collection is not too threatening Earth because in a relatively stable position because of bound orbits the sun.
But scientists predict that there are a number of stars of the solar system and nudging comets orbit the sun. Stars with fractions predicted comet hit the Earth. Rain could comet plunged Earth.
"Star passing near the Sun can make incoming comets and the solar system collide with the Earth," the Bailey-Jones wrote in his paper, as quoted from Dailymail.
The most dangerous star named Hip 85605 with the smaller size of the sun.
Bailey-Jones consider there is a possibility of 90 percent that the star is moving as far as 0.13 to 0,65 light years takes about 240 to 470 million years.
Light year is a unit of length, defined as the distance light travels in one year pass through the vacuum of space.
The analysis results obtained based on data from the Hipparcos plane belonging to the European Space Agency (ESA), which was flown to scan the sky in the 1990s.
German scientists said, the estimates about the stars that will be close to the solar system that is the most accurate at this time. But he stressed could not confirm the position and movement of Hip 85605 today.
Furthermore, the Bailey-Jones said there was another star who also threatened, called GL 710, which has a 90 percent chance of arriving to Earth in the distance range of 0,3 to 1,4 light-years away in the period of 1.3 million years.
Not only Oort Cloud comets, radiation from these stars also could threaten the Earth's ozone layer through erosion scenarios.
"When the star turns into a supernova in a collision, and quite intense, it could be radiation to kill organisms directly," said Bailey-Jones.
''The ozone layer is eroded radiation that causes life on the Earth could be destroyed," he added.
