Small asteroid flies close by Earth

On 3/20/2009, asteroid 2009 DO111 flew past Earth only about 288,000 miles away--just beyond the orbit of the Moon! About the size of a football field, this dangerous space rock was visible in backyard telescopes as it sped through the constellation Cassiopeia shining at 13th magnitude, far below naked eye visibility.

Here is a nice photo taken
