Here is a bit more on how they calculated the position of the star that came so close:
Researchers observing the stars found that by recording the change in distance from the Sun to the stars and the star’s motion across the sky they could determine the trajectory of the ancient objects. By tracing its movements back in time, they found its close shave with the Sun occurred as recent as 70,000 years ago. The binary star system has a low mass and it was speeding by our solar system at the time which means that the effects caused on the Oort Cloud were very small. Currently Scholz star lies around 20 light years away in the constellation of Monoceros, so at least we haven’t got to worry about that happening again. Or maybe we have… Dr Mamajek of the University of Rochester estimates that a rogue star probably passes through the Oort Cloud every 100,000 years, or so.
Needless to say, we’re glad there was enough distance although it would have been cool to see!  Maybe next one 😉
We hope you like the video and check back for updates on this story as they figure more out.
thanks to TheVendor101 for the great info

a shooting star will swalow the earth if it get close .and other planet close to it.
It would completely dismantle our orbits, shoot us out of the solar system. Highly doubt it.
That’s how life started
How in the hell would anyone ever know that???
70,000 years ago the earth’s climate underwent a dramatic and drastic change, in which the human race was brought to the brink of extinction. At one time our species entire population was reduced to 20,000 people.

Bullshit
.8 light years isn’t all that close as your sensationalist title suggests. Close for something that size, sure, but we wouldn’t have even seen it since it was a brown dwarf
.8 light years is close enough
Guys check flat earth groups you be surprised just go now and will change your life forever. ……

Well I don’t think it would be remembered easily – that was kind of a long long time ago…..
No it wont. Look up Pythagoras do a 20 min experiment and it will destroy any arguement flat earthers have.
Ka boom sike but almost
Good one lolololol!!
