A curious object is going to pass within about 80,000 miles of
the Earth, that's only one-third the distance to the
Moon, visible from 7pm tonight, January 12, to 4am tomorrow morning.
Catalogued as a 10m-class asteroid, 2010 AL30 has an orbital period of
almost exactly 1 year. There is some mystery surrounding the object as it is
difficult to classify whether it is manmade or natural in origin. The object
will pass through Orion, Taurus, and Pisces and experienced amateur
astronomers are encouraged to monitor the flyby. There is more
information available
