Hi List: I am trying this again since my previouys forward did not appear to go through.
On November 13, this newly-discovered asteroid (only about 20 meters diameter) will pass within 2 Earth radii of the CENTER of the Earth (that is close). It will be 9th magnitude (about 50-100 times too faint to see with the naked eye), but show be observable with a small telescope (if it is night where you are when it comes by and you know were to look). Go to the cfa.harvard site for coordiantes, etc. I can interpret columns if you are interested. I am sure there will be more about this in the coming days.
