Another Solar System coming to Collide with ours

Ok, I cant find any information on this on anything i saw it last night on someone named Don Adams facebook page ( He was with the whole Nibiru stuff. ) I do not believe in this just was looking for some interesting reads.

Tho he is saying that the Comet C/2013 A1 that could hit Mars was sent by this Solar System and was wondering if anyone knows if this Comet has come into the solar system before.

Could another Solar System coiled with ours ? The reason i ask this question is cause the Galaxy moves with its arms in one direction. So isn't everything moving technically in a circle ?, I know there are Star's and Roug planets that are moving in diff directions i just dont know if a Solar System could ?

And my final question is we would know about it correct ? I mean we can see pretty far out, and i find this pretty stupid to even put out there after so many people have been wrong so far.

"He was with the whole Nibiru stuff." really tells you all you need to know. They never let that whole "breaks the laws of physics" thing stop them from insisting that the end was coming. And when it didn't, they simply switch to a new doomsday scenario.

If you think about it, trying to send a comet from one solar system to another is a pretty stupid way of trying to wipe a civilization out--any extraterrestrials advance enough to do that certainly would have more efficient ways of taking us out.

BTW, he doesn't claim this system is called "Klendathu" did he? I only ask because it's basically the plot of the book and movie "Starship Troopers", except the bugs on Klendathu used asteroids (which actually makes a tiny bit more scientific sense--a planet killer asteroid would be harder to detect)

This is 2013/A1's first pass through the solar system, and since the eccentricity of the orbit is greater than 1, we won't see it again. A lot of comets do that, especially if they come from the Oort cloud, as this one apparently does.
