Description:
Explanation:n(written by R. P. Binzel, MIT)nThe sixth closest asteroid encounter on record, the May 29 near-miss by the object catalogued as “2012 KT42”, was tracked by the NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii as it whizzed inside the orbital distance of Earth geosynchronous satellites (6.6 Earth radii or an altitude of 22,000 miles). KT42's discovery by the Catalina Sky Survey 23 hours before closest approach allowed time to trigger a preplanned “Rapid Response Pro

However, the asteroid was traveling at 17km/sec (38,000 mph) and came 2.5 times closer than our geosynchronous satellites. It was far too small to make it through our atmosphere anyway. Each image is a 3 second exposure, during which the object moved, creating a trail. The images were taken on 2012 May 29 between 4:30 and 6:55 UT, the latter being 6 minutes before closest approach.

This covers from 9:20 to 11:09 p.m. CDT, taken from a moderately light polluted site in Huntsville, Alabama. The asteroid appears near the left edge then crosses to the right, with passing clouds obscuring the asteroid about half the time. The clearest view is near the end of the video. Canon 6D with Canon 200mm f/2.8 lens at f/4.0, 10 sec exposures every 12 sec, ISO2500. Star tracking with an Astrotrac.")
