Comet C/2014 E2 (Jacques)
According to Fred Willard, "Astronomers recently discovered that comets are merely asteroids that are 'freaking out for some reason.'"
The image below shows how much the comet had moved in just under 10 minutes.
And in a couple of hours.
And with a couple of photobombing satellites.
The image below shows how much the comet had moved through the Coathanger in 45 minutes on September 19th/20th.
