Discovered by the Catalina Sky Survey on 6 October 2013 a week before its last close flyby of Earth, 30-metre-wide asteroid 2013 TX68 was initially thought to pass by Earth again on 5 March 2016. Additional observations of the body have now been obtained, refining its orbital path and moving the date of the asteroid’s close brush with our planet to 8 March.
NASA has formalised its ongoing program for detecting and tracking near-Earth objects (NEOs) as the Planetary Defense Coordination Office (PDCO). The office will be responsible for supervision of all NASA-funded projects to find and characterise asteroids and comets that pass near Earth. It will also take a leading role in coordinating efforts in response to any potential impact threats.
