An orange dwarf called Gliese 710 in the future will be at a distance of 0.1 light years from the Earth is only 6 thousand times further away than the Sun and tens and hundreds of times closer than the nearest other star to date. However, by human standards, this will happen very soon (but not soon by the standards of space and even by the standards of an Earth-like planet) is about 1 350 000 years assuming the Polish astronomers.
Gliese 710 is a single star in the constellation of the Serpent. It is an orange dwarf, 2% less massive and up to 30 times less bright than the Sun. Now she is at a distance of about 45 light-years from the Solar system, however, as scientists have suspected before, gradually moving closer to her, reports life.ru. Previously it was assumed that the minimum distance between Gliese 710 and the Sun is 4 light-years — about the same as today separates the Earth from Proxima Centauri.
To check these estimates, is not subject to revision since the nineties of the last century, experts have studied the data obtained with the European Observatory Gaia. As a result, experts came to the conclusion that the star will be 40 times closer to Earth than expected. This leads to the fact that the star will be the brightest after the moon and Venus point in the night sky. However, other potential impacts may be significantly less pleasant.
The convergence will be outraged by the comets of the Oort cloud, located at a distance of 1.5—2 light years from Earth. The result of the comet, these would come in motion, and many of them, according to the forecast of scientists, over the next million years will collide with the Earth. However, if the Earth will face really large space body, it can lead to such catastrophic consequences as mass extinction.
