An Near-Earth Asteriod

On 9 November, 2012, Asteroid 2005 YU55 passed by the Earth. In this video the asteroid moves through the field of view of Swift‘s Ultraviolet/Optical Telescope (UVOT) shortly after the space rock made its closest approach. The video plays on a background image from the Digital Sky Survey that shows the same region, which lies within the Great Square asterism of the constellation Pegasus (times are UTC).
