A Star is Hurtling Towards our Solar System could cause a Devastating Comet Bombardment



Published on May 2, 2017
Bad News for our solar system. The huge gravitational force of star Gliese 710 as it passes through the Solar System could trigger a shower of comets in the direction of Earth much sooner than anticipated warn experts.

The star could come as close as 1.2 trillion miles of Earth. While they may sound like a really long distance, in space terms this is significantly close. In fact, Alpha Centauri, the closest star to Earth is located some 25.67 trillion miles away.

For decades, scientists have known that the star that most threatens Earth and our solar system, in general, is Gliese 710, which at some point will travel extremely close to the Solar System.

However, a recent study published in the journal Astronomy and Astrophysics suggests that it will come much closer than thought and that its arrival could provoke a shower of dangerous comets in the direction of Earth.

According to the scientists, the star is 64 light years from our planet and, although it will not collide with any celestial body, its passage through the Oort Cloud — an extended shell of icy objects that exist in the outermost reaches of the solar system— would trigger a shower of comets in the direction of Earth given the enormous gravitational influence of the star.

Filip Berski and Piotr Dybcznski of the Adam Mickiewicz University in Poland and co-authors of the study used data collected by the Gaia spacecraft which showed that both the distance and time of proximity are lower than those proposed in previous studies. Berski and Dybcznski indicate that the star’s minimum distance to our solar system will be almost five times closer than previously thought.

Their paper was published in Astronomy & Astrophysics, a research journal.

Thus, the Gliese 710 could trigger a swarm of comets in around 1.35 million years.

- Close Call! 'Scholz's Star' Grazed Our Solar System 70,000 Years Ago -
A dim red dwarf and its brown-dwarf companion likely grazed the outer edges of the solar system 70,000 years ago in what scientists say was the closest encounter ever between our sun and another star.

At its closest approach, the binary pair — known together as "Scholz's star" — passed by the sun at a distance of less than 1 light-year, according to a study of the binary's velocity, researchers said. One light-year is the distance light travels in a year — about 6 trillion miles (10 trillion kilometers). The nearest star to the sun, Proxima Centauri, is 4 light-years from Earth.

Scientists made the Scholz's-star discovery by measuring its tangential velocity (the motion across the sky) as well as its radial velocity (speed away from Earth).
