"There's also been a theory that a rouge planet will sweep in and either: 1) Collide with Earth, 2)Collide with the Moon 3) Near miss, causing tidal forces and disaster, 4) take up orbit with us, etc. 5) rip us away from the sun,etc."

I know there was a pseudocult based on fearmongering over this.

I can remember being taught about "Planet X" in elementary school. I always wondered if it was an imagined memory. Thanks @O my captain for your explanation.

You were taught about Planet X in elementary school? Fnord didn't take, huh?

Well, the person who told me about this also believes in the Mayan calendar schtick, contrail conspiracies and Ron Paul, so...

The "planet X" name became "Pluto" when it was discovered, in the mid-1930s, I believe. So, you would have had to have been in grade school then... making you, oh, 80 or 90 now, I would guess.

Seriously, I think they must have been refering to some other concept, or else, they where trying to stimulate young minds with the concept of the unknown being out there, just waiting to be discovered, etc...

Not to scare the fuck out of all you, but as far as the 'journey to the far side' film goes, I read recently that there really IS a large rock-a trojan asteroid- out there in orbit with us -- though it's sort of ahead of our path, not opposite. it's called 2010TK7.

Reading about 2010 TK7 has been very interesting. I was not fully aware of the significance of Lagrangian points and the possibility of objects being in such unusual orbits.

Thanks for the contribution, RacerX.

Actually, to back up David on this one, I as well was taught in elementary school (in the 80's) about Planet X. Although it was located AFTER Pluto.
