Scientists said the ability of the star to “bombard” the Earth with comets


The passage of stars in a certain vicinity of the Sun can affect the activity of the Oort Cloud, sending comets into the Central part of the Solar system including the Earth. Scientists using a satellite placed in orbit of the telescope is investigated more than 300 thousand stars and identified those that are really able to provoke a “bombardment” of our planet by comets.

To “Wake” of a comet in the Oort Cloud, the star must pass at a distance of approximately 60 trillion miles from the Sun. Of these numbers only 97 stars will approach the Sun at a distance of 150 trillion kilometers, according to the European space Agency (ESA). And here’s another 16 stars in some point will be at a distance sufficient to impact the comet on those 60 trillion km.

The most dangerous from this point of view, the star Gliese 710. Research has shown that it will approach the Sun at a distance of 2.3 trillion miles. The good news is that this will not happen soon – in 1.3 million years.
