asteroid 2012 DA14 next week
If I go out on Valentine's day next week with binoculars and clear sky at
the Plough and manage to see this object going zenithwards across the handle
of the pan-handle 21:00 to 22:00 or so, will it be varying brightness from
tumbling. ?
If it is tumbling before near earth encounter would that gravitational
encounter stop the the tumbling of an asymetric object?
