Default Gliese 710, means **** will hit the Earth?

https://en.wikipedia.org/wiki/Gliese_710

Gliese 710 has the potential to perturb the hypothetical Oort cloud in the outer Solar System, exerting enough force to send showers of comets into the inner Solar System for millions of years, triggering visibility of about ten naked-eye comets per year,[12] and possibly causing an impact event. According to Filip Berski and Piotr Dybczyński, this event will be "the strongest disrupting encounter in the future and history of the solar system".[13] Earlier dynamic models indicated that the net increase in cratering rate due to the passage of Gliese 710 would be no more than 5%.[7] They had originally estimated that the closest approach would happen in 1,360,000 years when the star will approach within 0.337 ± 0.177 parsecs (1.100 ± 0.577 light years) of the Sun.[14] Gaia DR2 now finds the minimum perihelion distance is 0.0676±0.0157 parsecs or 13900±3200 AU about 1.281 million years from now.[10]

Well, at least there won't be any humans around then, or any
intelligent species to know what might be coming.

Perturbation nonsense is due to the fact that they observe and model motions within the 365/366 day calendar system via RA/Dec - it might entertain those who know no better but it is from the same pseudo-science that infected the world with astrophysics.

If reasonable adults were around the whole thing could be sorted out but no such people presently exist which is dismaying,at least from experience.
