When first discovered thru Parallax it was around 2 LY away but now they say around 4 LY. I see they are to do another Parallax this year and see if any planets are with it. I think the Centarui system is dangerously close and the orbit can sling any thing towards us because of the north and south orbits.
It wasn't discovered through parallax. That is a means of determining distance, not discovering unknown objects.
Furthermore, its distance at the time of discovery was understood to be very near that of A Centauri, about 4.25 LY and thus your claim that the distance has been changed, either in books or in reality, is incorrect.
Your worries about that system harming ours are misplaced. Have a cup of coffee and relax.
Thanks I know enough to get me in trouble the thing is sometimes know not enough to get me back out of trouble.

The chaotic gravity tugs will do some damage (go ahead and panic), but no humans will be harmed (stop panicking) because we'll all be long gone (PANIC!) due to either inhabitable conditions on Earth (PANIC SO HARD) or some other natural or man made cause (PANIC REAL HARD) and not some biblical apocalypse (LOSE YOUR SHIT!!!)
That was so funny thanks
