Near-Earth asteroid 2013 RS43: an image (13 Sept. 2013)
On Sep 13 2013, at 16:07 UT the near-Earth asteroid 2013 RS43 reached a minimum distance from us of about one millions of km. Of course, no risks for us and this 14 meters asteroid is now on its way far from the Earth.
A few hours after the minimum distance, as soon as the object was above the horizon, the PlaneWave 17″ robotic unit was slewed to it and the mount was asked to track its fast apparent motion. An average of two, 180-seconds exposure is above, showing the minor planet perfectly tracked.
