You'll likely have no opportunity of seeing the asteroid. At it's brightest, it will require a good-size telescope to see. NASA and other astronomers will track it with radio and optical telescopes. For more information on asteroid YU55, go to the NASA website on the object at http://neo.jpl.nasa.gov/news/news171.html.
On Nov. 17-18, Earth crosses through the debris of comet Tempel-Tuttle, creating the Leonid meteor shower. Normally a so-so shower with about 20 meteors per hour, it holds the record for meteor shower activity with 500,000 per hour, back in 1966. We cross through the thickest part of the debris cloud every 33 years and last did so in 1998. But there are clumps of debris here and there along the comet's path, and we may see a meteor every minute or two. Best viewing time will be around midnight.
