was discovered yesterday on December 9th.
It is a small 36 meter Apollo class near earth object.
It makes it's close approach between Earth and Moon...
Earth --- 2012-Dec-11 --- 10:08 UTC --- 0.0015 AU / .6 LD
Moon --- 2012-Dec-11 --- 16:52 UTC --- 0.0021 AU
It will pass through the Earth's shadow, a very rare event.
