(367789) 2011 AG 5 is a near-Earth asteroid of the Apollo type . It was discovered on January 8, 2011 at the Mount Lemmon Observatory ( observatory code G96) of the Catalina Sky Survey . Its period is 1.7 years. With an estimated diameter of 140 meters, it represents a potential danger to the earth and is listed on the Turin scale with risk level 1. (367789) 2011 AG 5 will pass through the earth-moon system on February 4, 2040 at a distance of about 0.007 AU . This corresponds to an approximate distance of one million kilometers from the earth.
In June 2012, along with 2007 VK 184, it was the only property on the Turin scale with a risk value greater than zero.
On December 21, 2012, astronomers from the Gemini Nord Telescope on Mauna Kea gave the all-clear for the danger of an impact from the near-Earth asteroid.
