Iridium 33 (wreckage)
BRIGHTNESS: 2 (like stars in the Big Dipper)
Iridium 33 was severely damaged on Feb. 10, 2009, when it collided with the Cosmos 2251 satellite over northern Siberia. Nevertheless, a substantial piece of the original satellite seems to have survived--including the main mission antenna which sometimes glints brightly in orbital sunlight as the wreckage tumbles at a rate of 4.7 seconds. Try looking for Iridium 33 when it passes overhead. You may see nothing, but the possibility of a glint makes it worth a try.
