Asteroid (7482) 1994 PC1

[Buzzard75]

Video of Asteroid (7482) 1994 PC1 captured last night (Jan. 18, 2022) during the close flyby of earth. It is approximately 1.1 kilometers in diameter and has an orbital period of 1.56 years. Asteroid (7482) 1994 PC1 is classified as a near-Earth object (NEO) as it does cross the orbit of the Earth with a perihelion of only 0.9042AU. At the time of the video, the asteroid was moving at approximately 3775mph relative to Earth.

The video is a series of 10 second exposures with a luminance filter captured over the course of just under one hour. A monochrome camera was used so in order to add a little color to the stars I captured several images of the same region with RGB filters after the asteroid had passed and then following the normal process for stacking and combining of images with the luminance animation layered over the RGB image. Enjoy!

And one image to show the full path. The larger gaps in the path are where I dithered. Probably unnecessary for something like this, but I was too lazy to go in and change the settings.

That was a fast one. Very nice capture.

Fast and deadly if we got in the way of a 1 km asteroid..... Nice capture!
