After finishing two long imaging projects, a 60% moon made a good night to do some minor planet hunting. 3 Juno is a large asteroid in the asteroid belt. It is about the size of Indiana, and weighs as much 3,300 Mount Everests. It was pretty low in the sky for me at around -12 degrees declination in Aquarius, but it was a bright object at 8.64 magnitude during this observation, where it was at a distance of 141,855,974 miles. At this distance, its angular diameter was 0.233 arcseconds, or about the same as a penny at 10.5 miles away. It was moving relative to the stars at about 6.57 arcseconds per hour.
The following video shows it moving across the sky over 40 minutes relative to some background stars before it went behind the trees,
