On Oct 12, 2017, a small asteroid zoomed past Earth just outside the range of our geosynchronous satellites.
First discovered in October 4, 2012 during it's last close approach. It will make several more approaches in the coming decades, but nothing as close as this one. Next closest approach will be in October 2050.
Size is estimated 15 meters, with a non-spheroid shape, and has a fast rotation with a rotational period of only 12 minutes and 14 seconds.
A single 60 second exposure as the asteroid zoomed across the field of view.
