There may very well be a 10nth planeet orbiting Sol, but it's not Planet X. There has been a recent discovery of a large rock that orbits the sun outside of Pluto's orbit. Some are arguing that it's not big enought to be classified as a planet. Some also argue that Pluto isn't big enough either. I say, "who cares?" <br><br>We are going to be discovering a lot more large rocks floating between Pluto and the Kupier belt, the ring of rocks that occaisionally kick out asteroids now and then. But none will cause the symptoms your friend's listed. So relax. Let's worry more about the man-made "natural" disasters that are very real.
