Two Yale University students used the WIYN 0.9-meter telescope at Kitt Peak National Observatory to capture a series of still images of asteroid 2002 NY40 on August 15-16, two nights before it made a close flyby of Earth. The still images were made into a cool digital movie that shows the asteroid streaking across the sky over a period of two hours. According to an AP story the students were supposed to looking at some binary stars when they decided to look at the asteroid instead.”
