It seems that a small firestorm has erupted on the internet in the last few days over a time lapse video of an asteroid that narrowly missed a collision with earth. In this particular video a tiny "mysterious object" can be seen dancing to the left and right while simultaneously moving upwards in the frame, and it appears to move out of the way of the asteroid in the animation. This is caused by a hot pixel. Normally hot pixels are stationary from image to image, but when you realign your images to put them together into a time lapse where the stars remain stationary the hot pixel can appear to "move." It's actually tracing out the original motion of the telescope. I'm showing this video as a comparison from my 2-7-09 Lulin animation's red channel where there was a hot pixel near the top of the frame. The first segment shows the full frame, the second segment shows a zoomed in crop of the dancing hot pixel.

Tracked with an 8" Meade LX200 Classic and filmed with a Blackmagic Pocket Cinema 4K @ f/6.3.
Channel members get exclusive access to the RocketTraker software that I developed for Reds Rhetoric and myself to be able to track rocket launches and landings like this with off the shelf Celestron NexStar telescope mounts.
