"All-Clear" Asteroid Will Miss Earth in 2040
Gemini Multi-Object Spectrograph image of 2011 AG5. The asteroid is the point at the center of the image (circled) with background stars trailing because the telescope tracked on 2011 AG5. This single 300 second exposure is oriented with north up and east left - each background star streak is about 15 arcseconds in length. 2011 AG5 is highly variable in brightness and other Gemini observations on October 27th required longer exposures than the one shown here.
