"Sunlight reflected from the surface of the asteroid makes it shine like a
13th magnitude star".
I was always under the impression that 13th magnitude was very dim indeed,

What else is as bright as the ISS?
Thu, 26 Mar 2009 17:18:41 -0700 (PDT)
Is there another satellite which would appear approximately as bright

Neglected double stars

I have created a mini web site showing images of some neglected double

magnitudes between 10 and 12.
