Description

This asteroid made a "close" flyby of Earth and is considered to be a NEO. The video was taken the day after closest approach. (That occurred below my horizon) It was my first attempt to image an asteroid. I was shocked that I was able to capture it. It was moving quite fast. The telescope had to be constantly moved to keep it within the field.

I looked up the stats on the object and discovered that it is only 1.2 to 2 miles in diameter. At the time I imaged it, it was 4 million miles away and shining at 10.8 magnitude. Light travel time was 21.48 seconds.

I tried to image it again the next day, but it was already down to my horizon and out of reach for me.

Each image is a 20 second exposure with a 60 second delay in between.
