Planet x is very real. however, I'm pretty sure it wont appear until last quarter this century. But, until then, I feel there will be rogue comets and asteroids coming from the general vicinity that planet X is coming from. The one that's going to appear in 2013 will be brighter than the moon.

Also, does anyone remember that speeding X shaped body that they posted about a year or so back? I think they said it was the product of two comets or asteroids which had collided. Wonder where that's at right now.
