In 1.5 million years time, the solar system could be in for a rough ride.
An orange dwarf star named Gliese 710 is powering in our direction and an astronomer has calculated an 86 percent chance of the interstellar interloper smashing through the Oort Cloud, located in the outermost reaches of our solar system.
This could have the devastating effect of scattering the icy Oort Cloud objects (or OCOs), causing them to plunge toward the sun and the inner planets, potentially bombarding Earth with comets.
Vadim Bobylev of the Pulkovo Astronomical Observatory in St Petersburg has published revised calculations of local star positions and velocities to arrive at this prediction.
In 1997, the European Space Agency's Hipparcos spacecraft analyzed data from 100,000 stars, compiling what is known as the Hipparcos Catalogue. 156 of these local stars are of particular interest to astronomers as the sun was thought to be a lot closer to them in the past and there is a high possibility they will make a close approach again.
