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?




Yes.
No.

Would the brightness variability be perceivable by simple looking through
binoculars (if seen at all) and over what sort of periodicity?
