Asteroid 2002 UY1 Passing by NGC 1055
14-Nov-2015
While looking through the data captured last night of NGC 1055, I discovered an object slowly moving through the field of view. It seems to be moving much more slowly than a satellite, so I can only conclude it must be an asteroid. Thanks to Le_Baron on Reddit, the asteroid was identified as 2002 UY1.
