2005 YU55

So i am surfing the internet, doing my usual looking into space, and interesting facts when I come across NEO 2005 YU55. NEO; standing for Near Earth Object. I happen to be looking into the WISE outer orbital scanning satellite when I came across JPLs NEO up to date list. Asteroids from the 1800's all the way to the year 3000. When I see that on November 8th, 2011 NEO 2005 YU55 will come within 0.81 AUs of earth. Or around 200,000 miles. That may see like a great distance, but that is closer than the moon. Were talking 2.5 earths circumferences away. And at 1/4 a mile in diameter...I kinda stared at the screen for about 2 minutes grasping this. Then came a little more research and the realization that this thing was essentially on a different orbital plane than the earth/moon and was not even categorized as a level 1 threat. So be safe america...but keep your eyes open.
